Will calling emacs_abort give us enough information about who's the
culprit?
How about this alternative idea: write a replacement waitpid, which
will check if it is called by someone other than our main thread, and
with its first argument negative, and then produce a backtrace or some
message to stderr? Would that work to trap calls to waitpid from GTK?
