The hard part looks to be cancelling/changing the timer, which means 
that we can't just create a set and forget listener thread for a given 
timeout. Otherwise that seems to me the straightforward approach.

But maybe one of the Windows wizards has a better idea.

I doubt the changes would be very invasive - with luck just confined to 
timer.c.
