For better or worse, much of what you have discussed have been fleshed out
about two years ago in this mailing list and in stackless. Also I outline
strategies in the PyCon 2008 talk "Adventures in Stackless Twisted
Integration." Personally, I don't know why more people don't use Stackless with
Twisted.
Some advice:
1) Based on what I have seen, you don't need to write a custom reactor (I still
remember Glyph setting me straight on that one). At least for what you are
doing :-).
2) Use task.loopingCall to make the reactor periodically yield.
l = task.LoopingCall(stackless.schedule)
l.start(.01)
however there is some weird interaction between Stackless Python 2.6 and
Twisted so you may have to do
task.LoopingCall(__tick__)
def __tick__():
stackless.schedule
or play with the recursionlimit variable. I have not gotten to the bottom of
that problem.
Cheers,
Andrew
