well that is an issue. however the other types of thread implementations
(userland process) _are_ limited to one CPU. linux threads can migrate
between processors since they are ordinary processes. of course there are
issues when you have threads across processors -- cache thrashing and
problems with sharing the memory segments.
i dont think anyone has a good solution for threading unless one goes to a
microkernel -- since ukernels have explicit message passing between
threads, they are inherently mroe suited for MP boxes.
