Just a few questions:
1) Under what conditions does atomic not work?
Hm. I thought you meant *your* atomic didn't work. We should really
be worried
(well, me, at least!) if .set_atomic doesn't work! Can you generate
a test case?
[I didn't look at all your code carefully... it's not clear to me how/
if you are
doing automatic scheduling. ...Oh... Did you read
carefully? .set_atomic does
only stop *automatic* switching of control... explicit passes (e.g.
send) can
still "switch" tasklets...]
2) Will stackless switch to another tasklet when entering blocking
routines
(like IO), I know threads do this...
No it won't. In fact, it fundamentally *can't* (since it "runs" in
only one thread).
3) Does anyone know where to find how many commands python processes
before it
tries to switch threads (I remember something like that happening?)
It's not really "commands"... more like a number of loops through the
code interpreter.
Did you mean "threads" or "tasklets"?
If you meant "threads" the answer is complicated... if you meant
"tasklets"
then see the parameter to stackless.run.
print stackless.run.__doc__
