Ok. So the problem is POE::Loop::Prima. It is not handling
AnyEvent::Fork when "run Prima" is called. I had to force Prima to use
EV as the loop and call Prima;:Application->yield in a timer. I could
then replace "run Prima" with an AnyEvent->condvar->recv call and things
work fine.

I had to just delete the AnyEvent::Fork object which I was storing in a
hash to access from elsewhere. Once this deletion is done, I can
recreate it later and it still works.
