    < frhodes> how can I replace an existing running server with a new one
      without rebooting?
    < antrik> frhodes: depends. if other critical things depend on it, you
      can't. there is no mechanism to serialize and pass on the open sessions
    < antrik> in some situations, you can orphan the old translator while
      starting a new one, so the previous clients will stay with the old one
      while new one will get the new one
    < antrik> obviously that only works for things that aren't exclusive by
      nature
    < antrik> in some cases, you might even be able simply to remove the old
      translator... but obviously only for non-critical stuff :-)

    <braunr> mhmm, there is a problem with thread destruction

[[open_issues/libpthread/t/fix_have_kernel_resources]].

    <braunr> actually, translator self destruction
    <braunr> if a request arrives after the last thread servicing a port set
      returns from mach_msg because of a timeout, but before the translator is
      detached from its parent, the client will get an error
    <braunr> it should very rarely happen, but if it does, we could face the
      same kind of issues we have when a server crashes
    <braunr> e.g. sshd looping over select() returning EBADF, consuming all cpu
    <braunr> not sure we want to introduce such new issues

    <braunr> i don't think i'll be able to make translators disappear reliably
      ..
    <braunr> but at least, thread consumption will correctly decrease with
      inactivity
