Actually, I almost think we should just add a priority argument to each of the 
routines that creates a new kthread/kproc.  Perhaps allow a priority of 0 to 
let the thread run with the default priority.  Hmm, it looks like kthreads 
default to running with whatever thread0 runs at (PVM) which is probably not 
really ideal.  Having an explicit priority for every kthread would probably 
be best.  Most kthreads should probably be at PZERO by default I think.
