2001-09-28 <NotZed@Ximian.com>
* e-msgport.c (e_msgport_put): Write the pipe notification outside
the lock. This way if the pipe fills up because of too many
outstanding request, the queue isn't deadlocked. This only
happens wiht 4096 outstanding messages, so something is getting
VERY busy! Fixes #11121.
