> Sometimes during retrieving mail through pop3 in gnus I emacs loops infinitely in pop3-retr. It seems to be somehow connected with some buggy mail. Normally I didn't have time to investigate it thoroughly (I haven't used emacs debugger yet) but this time I think I've found out enough to make this problem fixed by someone.

The while should also test whether the `process' is still alive. Or else,
pop3-accept-process-output should somehow signal an error if `process' is
not alive any more.
