CPython vs. Jython/JPython

[Timothy O'Malley]

hola.

I admit I haven't been following this discussion closely.  Is there
someplace I can go to find a summary of the current state of affairs?

Does this mean Python will (officially) permit libraries that only
exist for one platform?

If yes, does this mean that I can dare hope for Stackless to be
included in CPython?  Perhaps, Stackless is not a "library", and
therefore does not count?

[In truth, I really want uthreads.  I'm not so interested in Stackless
by itself.  Sorry, Christian. :-) ]

thanx.
