This has now happened to me with both mplayer and gpg, so I am
beginning to suspect a bug in the process status handling code
...

Symptoms: Happens in long-running emacs sessions, and fails to
repro if you kill and restart Emacs.

When the bug bites,, emacs hangs waiting for the subprocess even
though the subprocess has quit. Happens for example when you open
a foo.gpg file. If this happens, the gpg process finishes
decrypting the file, but Emacs fails to notice that it is done,
and hangs. Hitting C-g produces the message "buffer *epg* has a
running process ...". If you answer "no" to  kill that process,
emacs continues to hang.  Checking status of the gpg process from
a different terminal shows that process' status as "defunct".

Similar behavior with mplayer as well.

This is on an oldish Linux box that is still running Ubuntu
Jaunty, but with updated libs for gnutls etc.
