So if I make a 'plugin' that declares a
twisted.application.reactors.Reactor in the way done so inside
twisted/plugins/twisted_reactors.py, how do I make twisted trial pick it
up? Or do I actually have to add it into
twisted/plugins/twisted_reactors.py? Or monkey punch it in? If so, where
do I bootstap it in? Trial seems to need the reactor before TestCases
are even loaded.

Thanks again for any help
