-There is another possible reason for preferring lower-level bindings:

The task is to create easy to use Hurd bindings for a language of the student's
choice, and some example servers to prove that it works well in practice. This
project will require gaining a very good understanding of the various Hurd

-[[!meta title="Convert Hurd Libraries and Servers to pthreads"]]
-
-[[!tag open_issue_libpthread]]
-
-The Hurd was originally created at a time when the [pthreads
-standard](http://www.opengroup.org/onlinepubs/009695399/basedefs/pthread.h.html)
-didn't exist yet. Thus all Hurd servers and libraries are using the old
-[[cthreads|hurd/libcthreads]] package that came with [[microkernel/Mach]],
-which is not compatible with pthreads.
-
-Not only does that mean that people hacking on Hurd internals have to deal with
-a non-standard thread package, which nobody is familiar with. Although a
-[[pthreads implementation for the Hurd|libpthread]]
-was created in the meantime, it's not
-possible to use both cthreads and pthreads in the same program. Consequently,
-pthreads can't presently be used in any Hurd servers -- including translators.
-
-(Thus it's impossible to use the [Hurd
-libfuse](http://www.nongnu.org/hurdextras/#libfuse) with any FUSE modules
-depending on pthreads for example.)
-
-Most of the conversion has already been done in previous efforts (see
-[[!GNU_Savannah_task 5487]]) -- but the tricky parts are still missing.
-
-The goal of this project is to have all the Hurd code use pthreads. Should any
-limitations in the existing pthreads implementation turn up that hinder this
-transition, they will have to be fixed as well.
-
-This project requires relatively little Hurd-specific knowledge. Experience
-with multithreaded programming in general and pthreads in particular is
-required, though.
-
-Possible mentors: Barry deFreese (bddebian), Samuel Thibault (youpi)
-
-Exercise: Try to fix one of the outstanding issues with the work done so far.
-It's not yet complete, and there hasn't been much debugging yet, so it should
-not be too hard to find something needing improvement -- but if you don't see
-anything obvious, feel free to talk to us about an alternative exercise task.
