Right. This was the primary discussion point around 
poll/select/kqueue/epoll. We all realize that this is horrendously 
inefficient. The Plan (TM), as I understand it, is to move this to a 
Twisted reactor and then use the appropriate reactor for the system 
at hand (kqueue, epoll, etc...).

Someone had mentioned libevent on Wed, and I'm considering writing a 
reactor for it, which would ease the portability issues further.

Nope, it's exactly the right approach.
