it's still rough, but i'm willing to put it into
lucio's cvs repository so people can hack
on getting it up to speed.  send me mail if you're
interested.

unlike the other os-specific modules, i think the plan9
one should include just the system calls and
then have the rest implemented as python code
rather than the fairly difficult c layering.

the eventual goal is to bring in the ``stackless
python'' patches, so we can have really cheap
continuations and build a csp-style threading
module that has neither stack overflow concerns
nor ridiculously large stacks.
