"stupid" might be a harsh word, but what you're doing shouldn't be
expected to work. I'm surprised that it has worked as well as you
suggest that it has.

You might want to check your ulimits. However, twisted 2.2 might have
been calling select() in any number of places. And Python 2.4.3 had a
bug in it which would have caused a problem regardless. And there might
be a bug in the interaction of random bits of code from twisted 2.5 and
2.2. Whatever the problem is, you're on your own trying to sort it out
until you can upgrade to a supported version :)

Please do not attach notices like this to messages on this mailing list,
given that the "addressee" in this case is the entire internet :).
