... I guess the question of interest is why are threads insufficient? I guess they have system limitations on the number of threads or other limitations that wouldn't be a problem with continuations?
Sam is mucking with thousands of simultaneous I/O-bound socket connections, and makes a good case that threads simply don't fly here (each one consumes a stack, kernel resources, etc). It's unclear (to me) that thousands of continuations would be *much* better, though, by the time Christian gets done making thousands of copies of the Python stack chain.
Well, what he needs here are coroutines and just a single frame object for every minithread (I think this is a "fiber"?). If these fibers later do deep function calls before they switch, there will of course be more frames then. -- Christian Tismer :^) <mailto:tismer@appliedbiometrics.com> Applied Biometrics GmbH : Have a break!
