That's the general idea, I'm afraid.  My impression is that
nobody has cared enough to get this to work well on
non-USABLE_SIGIO hosts such as Solaris and OpenBSD.
On these hosts, that 'waitpid' will hang until the
process finishes or some other random signal arrives.
So, for example, if you type M-x sleep 10 RET C-g,
then nothing happens for 10 seconds, until the
sleep returns.
