CPython vs. Jython/JPython

[Delaney, Timothy]

The BDFL has spoken :)

The real question which was posed I guess is "why can't they be maintained
by the same people?" To which the answer would have to be that the CPython
people have a limited amount of time, the two projects require different
areas of expertise, and that the source trees really cannot share
*anything*.
