I am using the uthread.py found at:

Right now I am simulating WS-BPEL's synchronization
mechanism with channels and it seems to be working.
So I am happy :-) Previously I tried it with uthreads
and that worked too.

That would be neat. The impression I have so far,
is that uthreads is a lower level Stackless library
for building mechanisms that cannot be built, or
incur too much overhead, using tasklets and channels.

Thanks for your help. As I learn more, I would
be happy to report what I figured out in the Wiki.

Cheers,
Andrew
