    sys/sys              thread.h 
  Log:
  Fix numerous bugs in the BSD4 scheduler introduced in recent commits.
  Primarily, do not try to get a spinlock from a hard interrupt (e.g. IPI)
  if spinlocks are already being held by the cpu.
  
  This will probably have to be made an absolute rule - no spinlocks at all
  in a hard interrupt / IPI (vs an interrupt thread).
