Thank you! I tried hard to keep the "asynchronous signal" and
"deferred cancellation" terms all consistent. It's all a bit of
a mouthful, so I'd be happy if we could have come up with simpler
language, but it's hard to write it any simpler without loosing
the exactitude of what I'm trying to say. I'm happy to see future
edits that simplify the language. At the very least we now say
something about this corner case so people aren't caught off guard.
