[Stackless] multiprocessing module and stackless threads

[Robert Babiak]

Thanks Richard.

but what do you mean by "monkeypatch it via stacklesslib" how/ where can i
learn about MonkeyPatching?

Then I would assume I would just run it as any other tasklet, which I would
suspect would solve several problems i have with passing events, and SQL
calls on the wrong thread.

If your web server uses non-blocking IO, then it shouldn't be
necessary to have two schedulers.  I imagine with Django, you would
monkeypatch it via stacklesslib and it would then work in a
stackless-compatible non-blocking fashion.

Stackless supports per-thread schedulers, and explicitly supports
interthread channel communication.  There is no explicit Stackless
support for multiprocessing.  If it opaquely uses threads, then it
works in the manner mentioning threads above.  If interthread channel
usage is not being used, then channels switch between tasklets on the
same Python thread.

Cheers,
Richard.
