After much consideration, and playing with PEP380, I've changed my
stance on this. Full blown coroutines are the proper way forward.
greenlet doesn't cut it because the Python interpreter isn't aware of
the context switches. Profiling, debugging and tracebacks are
completely broken by this. Stackless would need to be merged, and
that's clearly not going to happen.
I built a basic scheduler and had a go at "enhancing" the stdlib using
PEP380, here are some examples making use of this style:
After realising it was a dead-end, I read up on Mark's ideas, there's
some really good stuff in there:
If someone can explain what's stopping real coroutines being into
Python (3.3), that would be great.
