On the other hand, having to multiplex in userspace requires calls to poll() et al, _and_ explicitly handling state which the kernel needs to handle anyway -- including locking and all that crap. Given that an efficient and fairly-low-cost 1:1 implementation is demonstrably possible ;-) the necessity to do any kind of n:m work strikes me as extremely low. -- Matthias Urlichs http://smurf.noris.de ICQ:20193661 AIM:smurfixx - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
