I think the answer to your parenthetical question is "yes".

Pass.

I think lack of tuits is the main thing.  I don't know if there are
obscure bugs or something like that.

Like Peter said, I presume it's a play on "green threads".

I'm fairly sure that (a) the only person who can really answer your
questions is Armin himself and (b) Armin doesn't read
comp.lang.python.  I'll try to catch him on IRC and point him here,
but you might want to email him yourself...
