Point taken. This is really more like a throw (but I don't trust my
intuition enough to suggest anything right now :-P )..

No, it's because Emacs is blocking that this timeout mechanism has
been suggested. If the task were asynchronous there wouldn't be a
need for a separate timeout. We would just sleep a bit and check a
buffer from Lisp code, and repeat a fixed number of times or until
success, whichever comes first. It could used for any potentially
long-running synchronous task, whether I/O or a user-specified
Lisp computation.
