Alternatively, asyncore could just be deprecated, which would be a lot
easier to do, and people would start from the correct solution :)

Hm. That's a lot better than moving parts of Twisted, yes. I still think
it's silly.

Adding yet another event loop would just continue the tradition, I'm
sure; it took us quite a while to get to the quality we have now just in
terms of platform support. I suppose you could butcher our code by
ripping features out... but you'd just get a crippled piece of software.
The motivation is "so then people can move to something less suck"? Why
not just have them start from something good to begin with?
