In case it wasn't clear, I was proposing this patch for the current code
base. It fixes a lot of problems with the MT implementation on Win32 at
the moment. Certainly something needs doing before we can do a full
release of 1.3 on Win32.

I guess so, but surely MT (and certainly multi-fiber) code shouldn't
really be doing longjmp's? I've pretty much convinced myself that we
should strip out all the signal stuff from the Win32 code, and work with
events and polling/blocking-on-events to simulate signals. That's what
I've done to simulate to a graceful restart SIGUSR1 signal anyway.
