[Stackless] Stackless Digest, Vol 50, Issue 17

Hi Robert:

Stackless.run() starts the scheduler. The tasklets are
executed in a first-come-first-servered-round-robin
fashion. Ordering is changed when tasklets explicitly
yield with a schedule() or block on a channel.

I downloaded boto and took a quick look. I see urllib
and httplib. Unmodified, Stackless will block. Perhaps
if you use Richard Tew's StacklessModule and
monkeypatching, you can get boto up with little
modification. Myself, I use Twisted so I would have to
look more closely at the simpleDb protocol. I am sort
of interested myself now....

Cheers,
Andrew
