Sorry to step in here, but there's tons of example for
portable async APIs. One that I just adapted Samba to is the
API used in the avahi libs. You hand the avahi libs a set of
callback functions like "listen on this fd for read" and so
on, and you are called back by avahi when something
interesting happens.

This is definitely doable without the requirement for
threads. It may be a complex API, but async programming
never has been easy.
