Andrea, can you point me to the place where we interrupt async
compilations when Emacs exits?  Is that just a normal delete-process,
or do we do something else, like sending a signal?  Also, does the
Emacs subprocess invoked to perform async compilation spawn further
child processes, or is everything happening inside a single Emacs
process?

Armed with that knowledge, I will try to look at the code and figure
out why the compiling process crashes.

Thanks.
