Twisted is a pretty good suggestion in general. ;)

Twisted supports HTTP, but it does plenty of other things too. Generally
speaking, it's useful for any network application, plus some other stuff.
You're half right about this being simple though, and not needing Twisted
to solve the problem. The only thing you need to do to solve the problem
is avoid using either signals or threads. Interaction between the two is
very complicated and, as you've noticed, varies across platforms. Twisted
is solving the problem for you here by letting you do I/O without using
threads, making signals *almost* simple.
