The terms 'hard switching' and 'soft switching' constantly appear. 'Soft' switching is defined as cooperating switching. I will assume this is associated with a 'stackless.schedule()' or a blocked on channel.
Hard switching is defined as brute-force. However what is brute-force? Is this when Stackless is in pre-emptive mode and one is relying on the ticks?
This is a question for Stackless Python only, not PyPy, so you should post in that mailing list, not here :-) To answer it, it's not visible to the user: it's just two different implementations of switching. "Hard switching" is by actually moving part of the C stack away; "soft switching" is using a purely standard C approach. PyPy only has soft switching (but with the same Stackless interface).
