It depends. If you have several multi-threaded applications, scheduling
all of the same application threads at the same time can be a big win,
especially if they synchronize a lot (no 'unneeded' wait if the
unlocking thread has not cpu). Gang scheduling was made for that. This
necessitates some kind of processor sets. I think this functionnality is
available on Irix on Origin/2000.
