My patch is for Windows only.  While examining my Linux builds to seek out
the most desirable behaviour, I stumbled across the difference between my
Linux 1.5.2 and CVS builds.  I have no other Linux builds to try, but if
someone has a few versions handy it would be interesting to know exactly
where it changes (or indeed if others can even repro this behaviour).

It appears that cygwin on Windows aborts the 2 threads without error - ie,
sleep() silently returns early.

Yeah, I appreciate that there will always be platform differences - but I
still wouldn't mind knowing a "most desirable" behaviour should the platform
support it and anyone be bothered - if for no better reason than for me to
know what behaviour to check in for Windows!

Thanks,

Mark.
