+
+Some [[tschwinge]] comments regarding your proposal.  Which is very good, if I
+may say so again!  :-)
+
+Of course, everyone is invited to contribute here!
+
+I want to give the following methodology a try, instead of only having
+email/IRC discussions -- for the latter are again and again showing a tendency
+to be dumped and deposited into their respective archives, and be forgotten
+there.  Of course, email/IRC discussions have their usefulness too, so we're
+not going to replace them totally.  For example, for conducting discussions
+with a bunch of people (who may not even be following these pages here), email
+(or, as applicable, the even more interactive IRC) will still be the medium of
+choice.  (And then, the executive summary should be posted here, or
+incorporated into your proposal.)
+
+Also, if you disagree with this suggested procedure right away, or at some
+later point begin to feel that this thing doesn't work out, or simply takes too
+much time (I don't think so: writing emails takes time, too), just say so, and
+we can reconsider.
+
+Of course, as this wiki is a passive medium rather than an active one as IRC
+and email are, it is fine to send notices like: *I have updated the wiki page,
+please have a look*.
+
+One idea is that your proposal evolves alongside with the ongoing work, and
+represents (in more or less detail) what has been done and what will be done.
+Also, we can hopefully use parts of it for documentation purposes, or as
+recipes for similar work (enabling other programming languages on the Hurd, for
+example).
+
+For this, I suggest the following procedure: as applicable, you can either
+address any comments in here (for example, if they're wrong :-), or if they
+require further discussion; think: *email discussion*), or you can address them
+directly in your propoal and remove the comments from here at the same time
+(think: *bug fix*).
+
+Generally, you can assume that for things I didn't comment on (within some
+reasonable timeframe/upon asking me again) that I'm fine with them.  Otherwise,
+I might say: *I don't like this as is, but I'll need more time to think about
+it.*
+
+There is also a possibility that parts of your proposal will be split off; in
+cases where we think they're valuable to follow, but not at this time.  (As you
+know, your proposal is not really a trivial one, so it may just be too much for
+one person's summer.)  Such bits could be moved to [[open_issues]] pages,
+either new ones or existing ones, as applicable.
+
+
+# POSIX Threads Signal Semantics
+
+  * Great!  [[tschwinge]] had a brief look, and should have a deeper one.
+
+  * If [[jkoenig]] thinks it's mature enough: should ask Samuel to test this
+    (that is, only the refactoring patches for starters?) on the buildds.
+
+  * Then: should ask Roland to review.
+
+  * Documentations bits should probably be moved to [[glibc/signal]].
+
+
+## libthreads (cthreads) Integration
+
+  * [[tschwinge]] suggests to leave them as-is?
+
+
+## [[libpthread]] integration
+
+  * To be done.
+
+
+# Java
+
+  * [[tschwinge]] has to read about RMI and CORBA.
+
+
+# Joe-E
+
+  * For later.
+
+
+# GCJ
+
+  * [[tschwinge]] has the feeling that Java in GCC (that is, GCJ) is mostly
+    dead?  (True?)
+
+  * Thus perhaps not too much effort should be spent with it.
+
+    If the POSIX threads signal semantics makes it going, then great, otherwise
+    we should get a feeling what else is missing.
+
+
+# OpenJDK
+
+  * All in all, [[tschwinge]] has the feeling that a working OpenJDK will be
+    more useful/powerful than GCJ.
+
+  * We need to get a feeling how difficult such an OS port will be.
+
+  * [[jkoenig]] suggests OpenJDK 6 -- should we directly go for version 7
+    instead?
+
+      * What are the differences (regarding the OS port) between the two
+        versions?  Or this there something even more recent to be worked upon,
+        for new OS ports?
+
+          * Perhaps the different versions' OS port specific stuff is not at
+            all very different, so that both v6 and v7 could be done?
+
+  * They seem to have a rather heavy-weight process for such projects: confer
+    <http://mail.openjdk.java.net/pipermail/announce/2011-January/000092.html>,
+    for example.  Do we need this, too?
+
+
+# Eclipse
+
+OK for testing -- but I'd very much hope that it *just works* as soon as we
+provide the required Java platform.
+
+
+# Java Bindings
+
+
+## Design Principles
+
+  * Generally ack.
+
+
+### MIG
+
+  * Hacking [[microkernel/mach/MIG]] shouldn't be too difficult.
+
+      * (Unless you want to make MIG's own code (that is, not the generated
+        code, but MIG itself) look a bit more nice, too.)  ;-)
+
+  * There are also alternatives to MIG.  If there is interest, the following
+    could be considered:
+
+      * FLICK ([[!GNU_Savannah_task 5723]]).  [[tschwinge]] has no idea yet if
+        there would be any benefits over MIG, like better modularity (for the
+        backends)?  If we feel like it, we could spend a little bit of time on
+        this.
+
+      * For [[microkernel/Viengoos]], Neal has written a RPC stub generator
+        entirely in C Preprocessor macros.  While this is obviously not
+        directly applicable, perhaps we can get some ideas from it.
+
+      * Anything else that would be worth having a look at?  (What are other
+        microkernels using?)
+
+
+### `mach_msg`
+
+  * Seems like the right approach to [[tschwinge]], but hasn't digested all the
+    pecularities yet.  Will definitely need more time.
+
+
+# GSoC Site Discussion
+
+  * Discussion items from
+    <http://www.google-melange.com/gsoc/proposal/review/google/gsoc2011/jkoenig/1>
+    should be copied here:
+
+      * technical bits (obviously);
+
+      * also the *why do we want Java bindings* reasoning;
+
+      * CLISP findings should also be documented somewhere permanently.
+
+          * We should probaby open up a *languages for Hurd* section on the web
+            pages ([[!taglink open_issue_documentation]]).
