Can someone more knowledgable than me tell of the current status of
threads in Linux on SMP and some history ?
In particular:
* can two threads from the same process run on two different cpus ?
* what happens in event of cache thrashing ? Is there any code to
optimize for this situation ? (have no idea)
* are threaded programs guaranteed not to run slower on SMP in
comparasion to UP systems ?
* was this situation always this way (i.e. 2.0.*, 2.2.* and 2.3.*)
* is there any way for a process to request that it's threads should
run on the same cpu ?

thank you very much
