  Log:
   - Relax requirements for p_numthreads, p_threads, p_swtick, and p_nice from
     requiring the per-process spinlock to only requiring the process lock.
   - Reflect these changes in the proc.h documentation and consumers throughout
     the kernel.  This is a substantial reduction in locking cost for these
     fields and was made possible by recent changes to threading support.
