[Twisted-Python] twisted listening on UDP port, why?

[Jonathan Vanasco]

I'm trying to lock down a box, and came across a peculiarity with a twisted dameon -- it's binding to 0.0.0.0 for UDP on an arbitrary port

I can'f figure out why this is happening -- I'm not consciously/explicitly using anything on UDP, and the port changes every time I start up a daemon.

Does anyone have a clue what it could be?
