[...] of course, that's the other 10%. [or even smaller.] I never claimed M:N cannot be viable for certain specific applications. But a generic threading library should rather concentrate on the common 90% of the applications. (obviously for simulations the absolute fastest implementation would be a pure userspace state-machine, not a threaded application - M:N or 1:1.)
