[IPython-dev] Twisted reactor + IPython0

Noooooo ;-).  Please, don't start doing stuff like this without all of
us discussing the best direction.  The parallel computing stuff in
IPython1 is designed to work with IPython0 and uses a very carefully
crafted approach for integrating with the Twisted main loop.  Doing
something like this could easily break IPython1 for the many current
users - even if it is optional, I don't want it in IPython0.  More
discussion is needed first.  Sorry I don't have more time to
participate in the discussion right now - if you are interested in how
we are handling this in IPython1, please look at that code base.  What
ever ends up in IPython0 _must_ be compatible with that.
