i.e. just it is getting exceptions when doing nothing at all, so it
seems to be completely broken.
Have you tried this, or do you know where to begin looking at what might
be wrong?
I know very little about Twisted, but I seem to recall that it offers
a range of different reactors; if you can find where in bittorrent its
deciding to use the kqreactor, you might be able to force it to use an
alternate reactor (such as one based on select() or poll()).
If you can change the reactor and get something that works, that would
suggest some issue with the kqreactor, at least on 8.x.
