It's been merged to trunk, so it'll be in the next release... whenever 
that is. Twisted tends to release about once or twice a year but I don't 
think there's a schedule.

Are you able to test against a recent development version? It's rare for 
trunk to have regressions, so it should be pretty safe to run against a 
recent version if it fixes a crash you're having.
