I have pretty much no trust that we're maintaining
!HAVE_POSIX_SIGNAL. And none that we have that capability of doing so. I
seriously doubt there's any !HAVE_POSIX_SIGNAL animals and
873ab97219caabeb2f7b390268a4fe01e2b7518c makes it pretty darn unlikely
that we have much chance of finding such mistakes during development.
