Comment(by tibbe):

 Replying to [comment:14 dleuschner]:
 > I can't really say anything about epoll because I just looked at it
 today but I noticed a thing while looking at the strace output of the
 program Stefan posted.  I seems that epoll discards watched file
 descriptors when they are closed but the IO manager seems to think that
 the file descriptor is still registered with epoll.

 This is a known bug (#4514). Bryan has a patch that's almost done.
