:Yes, I'm telling you, if you add anything make it specific to the
:scheduler.  It doesn't not need to be in scheduler independant code.  We
:just need a new system call for binding a kse to a cpu.  This will be
:scheduler independant and then we can call a scheduler dependant routine
:like sched_bind(kse, cpu);

How could one retrieve the current affinity of a kse?  I sorta like the
linux method of set and get affinity and using a bit mask for the CPUs a
process can be bound to.
