Thanks for the help. It's indeed the python 2.4.3 bug. I changed it to
2.4.4 or 2.5. It works.
The adhoc way I did to epollreactor seems to work. Maybe I am lucky.

I don't know if this works. I've never tried it. The epoll reactor
implementation shares code from other parts of Twisted. It may be
the case that that code changed between Twisted 2.2 and Twisted 2.5
in a way which will prevent epollreactor from working. It may also
be the case that it hasn't.
