Non-blocking publishing in Python

Hello:

I'm trying to use the apps/publish.py module as a starting point for writ=
ing my
own simple publishing lib to work with repubsub. The script runs fine on =
its
own, but whenever I try to embed it in other code, I seem to get blocking
issues and the CPU load spikes.

Inside the apps/publish.py script, I looked at the following method calls=
:

  asyncore.poll()
  scheduler.timeout()
  scheduler.run()

Now Python's asyncore does not have documentation on the poll function, a=
lthough
in my interpreter, I do see a reference for poll. The two scheduler funct=
ion
calls both pass in their implementations. If I comment out that loop, my
messages don't get published. So what's going on here?=20

Ideally, I'd like to be able to use Twisted's Deferred mechanism to handl=
e the
blocking issue, but I'm unsure the best way to approach it without heavil=
y
modifying the code base.

Any help is greatly appreciated.

Thanks,
Brian
