Just for the record, we are fully committed to having the core of
IPython depend on nothing outside of the standard library.  This point
is non-negotiable.  Here is why:

1) IPython needs to run on Jython and IronPython

2) IPython ships on the OLPC.   Space is a huge concern on this
platform.  If we required Twisted (or other big things) we would risk
begin removed from the OLPC distribution.

Thus, while we can use Twisted for some things, we do need to keep it
out of the core completely.
