Hi,
Anyone who can answer my previous question - "what if my greenlet needs to call
multiple Web services or that it's a long running one? In those cases the
greenlet will be blocked and resumed many times. How does PyPy handle that?"
Thanks.

Thanks Armin.
I dug around and found an email from you titled "Stacklets". Is that the new
solution?
If I understand correctly, in this solution a greenlet could only be suspended
and resumed once. But what if my greenlet needs to call multiple Web services
or that it's a long running one? In those cases the greenlet will be blocked
and resumed many times. How does PyPy handle that?

No, I think you are confusing two topics. The existing Stackless
PyPy, which does no C stack manipulation, doesn't work with the
JIT
without a lot of careful work. This solution is deprecated now. The
new solution, which does C stack manipulation, works with the JIT out
of the box. Both solutions are "implementation details" only; you get
the same tasklet/greenlet API to work with.

Yes. The next release is likely to be 1.6.1 soonish.
A bientôt,
Armin.
