bug#15534: 24.3.50; Emacs aborts at startup upon SIGTERM

[Barry OReilly]

[-- Attachment #1: Type: text/plain, Size: 9477 bytes --]

I started Emacs and while it was starting I killed it with a simple
'kill' (SIGTERM default) and Emacs core dumped. I presume SIGTERM is
meant to cause a more controlled exit. I was opening Emacs over an
'ssh -X' connection which was being rather slow.

Program terminated with signal 6, Aborted.
