A quick note on this piece: Though it's still a work in progress with
a few things that need to be improved, I've tested this on a whole lot
of different OSes now. I originally tried to use realtime signals
(big mistake), but after a couple of reworks I think it's starting to
look plausible and quite portable. Of the ~10 or so OSes we support
and test in the build farm, ~8 of them have this API, and of those I
have only one unknown: HPUX (I have no access and I am beginning to
suspect it is an ex-parrot), and one mysteriously-doesn't-work: NetBSD
(I'd be grateful for any clues from NetBSD gurus and happy to provide
build/test instructions if anyone would like to take a look).
