The Jython buildslave currently throws the following  error with Jython 2.5.1 trunk:

All this code exists to support non-threaded systems. I suspect some other stuff would break there, so I would remove all of that. Thoughts?

Looks like it's a Jython bug:  http://bugs.jython.org/issue1079

Closing as invalid.

And it's back to #3718 with latest jython trunk:  http://buildbot.twistedmatrix.com/builders/ubuntu64-jython2.5-select/builds/254/steps/trial/logs/stdio
