I can reproduce this on GNU/Linux (x86_64-unknown-linux-gnu, latest
emacs-24 and trunk).

ps shows the process as "[sleep] <defunct>", which stays until Emacs
exits.  Emacs 24.2 does not have the same problem.

If you are looking into it now, I can wait till I hear back from you
before making the pretest.
