Well, except... The last I heard there were still a few nasty bugs left
with garbage collection, and also especially with interrupts: seems
that under Windows there really aren't any user "interrupts" the way
we know of them in Unix/Linux. Instead, when your application process
starts up Windows has this weird way of silently forking a thread for
you that waits for "interrupts" and then wakes up to handle them. Getting
the stack-handling and stack-fixups correct between the CMUCL thread(s)
and the system-supplied "interrupt" thread is... uh... interesting.

But I've probably garbled something, so...

Carl? Give us an update, eh?  ;-}
