For what it's worth, I'm not surprised at this. In doing my first project that I did with twisted (my submission to the ClusterHQ puzzle) I ran into 3 or 4 little hiccups like this when I tried to use twisted. I think this was actually one of them. I basically had to write my unit tests as if I didn't trust any of the twisted utilities 😢
