You may wish to ask on POE's mailing list. I assume the higher concentration of POE users will help. irc.perl.org #poe is another place to ask, if you want shorter, more immediate answers, but it's better to ask on a weekday.

I'm biased, but I can objectively point out that POE has a lot of internal checks and external tests. The project has over 2500 commits and is almost 11 years old. Here are some more objective statistics about the project.
