Thanks Kevin for your patch.  I've tried it out and it seems to be fine,
so I installed it (at long last).
We're really relying too much on undocumented parts of the GPM API, tho.

If running with

	(gpm-mouse-mode 1)

and if you stop the gpm server, then emacs dies with

	Fatal error (6)Aborted

Output from "bt full" below; xbacktrace printed nothing at all.


The backtrace shows it at the abort() under the EBADF case in
wait_reading_process_output().  I think when Gpm_GetEvent gets an eof
from the server it closes gpm_fd; maybe that's the bad fd in question.
