Framework code that gets imported by the reactor you want to install
*must* not cause the default reactor to get installed, of course (nor
must any framework code which is imported by twisted.scripts.twistd).
However, as far as I know any other framework code may import it
If it's a trivial fix and a patch is supplied I don't suppose anyone
would mind applying it, but I don't think there's much point. Just
follow the advise above and you should be all set no matter what.
