More history: Emacs used to call signal to break out of the X error
handler before GDK had a chance to call _exit.  Until recently a longjmp
out of the GLib event loop would only cause lots of warnings to be
printed, so that call to signal would avoid the code path where GDK
would deliberately shut down the application.

That was replaced by a call to abort some time ago since the warnings
tended to make Emacs slow and flood .Xsession-errors with up to 50 GBs
of warning messages.  But since recently the call to signal cannot work
anymore, since GLib will immediately crash upon next entering its event
loop.
