I found ticket 2484 which is (I believe) about making Twisted
translatable to Python 3.x with the stock 2to3 tool:

I've added a comment about all the DeprecationWarnings issued by
Twisted's test suite when run under Python 2.6's 3.x-compatibility
warning mode; there's an awful lot more than just the 24 that cause test
failures.

I've also filed a bug about fixing one of the warnings mentioned, the
one about has_key() being removed in 3.x:

There's a few other warnings for which cleanup patches would be a good
lazy-afternoon effort. :)
