This isn't a simple problem. (Why is that so many people who have a problem say "I know it's a simple problem". If you know enough about the problem to know it's simple, why not solve it yourself instead of taking the trouble to post here?)

You don't say much about your specific problem, but this looks like you have a race-condition, or even deadlock. If both ends of the connection are doing a blocking read, they'll wait forever. You need to carefully synchronize your programs, and may want to use non-blocking reads. Perhaps by using 4-arg select, Event.pm, POE, and whatever it is Uri is always promoting (Stem?).
