I'm sure I could find another way if it comes to it. The original
proposal had a sleep(0.1) loop... I thought this was more elegant, but
obviously I didn't know about this portability problem and there are
surely other ways. (Searching for sigwait in the archives brings up
some fun discussion of other long forgotten dinosaurs that also had
this problem.)

Yeah I was thinking about that. I've just got a shell on an illumos
VM and will try a couple of ideas out if I can remember how to drive
this thing... more soon.
