Yes.  But it doesn't make sense to seriously debug Emacs in any other
way.  And the MPS build, in particular, needs the setting of SIGSEGV
to avoid stopping due to GC.

That's true, but people who don't have .gdbinit and the sources cannot
usefully debug Emacs anyway.  So I'm not worried about that.

The advantage of this method is that it affects only those who debug
Emacs, not everybody else.  That's a significant advantage in my book.
