Practical reality says that I won't get to this before the next version 
of Windows is released.
I don't want to promise something I can't deliver.

I seem to remember being slapped about for daring to suggest using a 
threaded embedded
language even if only one thread calls into the core, on the ground that 
the signals might not
go to the right thread.  So I'm assuming that a thread-aware build would 
generally mask async
signals and wait for them in a specific thread in sigwait, which would 
effectively match the
Win32 model (for a threaded build).

On the other hand, I'd normally regard signals as the work of the devil 
and prefer to send
a wakeup via some other IPC, for pretty much that reason, but there you go.
