I like POE, especially POE::Component::Client::AMQP.

I like mod_perl. Lots.

But if I try to 'use POE;' from within a mod_perl Response handler, Apache2 crashes in a relatively ugly way:

Is this a known issue? Is this caused (or exacerbated) by the use of mpm_event? After getting used to using the PoCO:Client:AMQP API, I'm not eager to go learn a new AMQP API just for web clients.

Is there some other way to do this?
