Emacs with a network process aborts on SIGTERM

[Lőrentey Károly]

Try the following:

	$ emacs -q -f server-start &
        [1] 12362
        $ kill %1
        [2]+  Aborted                 (core dumped) src/emacs -q -f server-start

The abort seems to be caused by this change:

2004-06-07  Kim F. Storm  <storm@cua.dk>

	* process.c (Fdelete_process): Undo 2004-05-28 change.
	Instead, call status_notify also for network process.

I have installed a change to inhibit redisplay during emacs shutdown.
