It should actually be using TerminateProcess (depending on the Twisted version being used, the relevant code is either in twisted/internet/_dumbwin32proc.py or twisted/internet/win32eventreactor.py, in the signalProcess method in either case), but even this doesn't seem to be a completely reliable way to end a process.  Twisted's buildbot has run into this problem as well, but we haven't figure out how to fix it yet.  Suggestions welcome - patches even more so :)
