- Adjust comment noting that handling of CPU limit exhaustion is done in

  ast().
- Actually set KEF_ASTPENDING so ast() is called.  I think this is buggy
  for a process with multiple KSE's in that PS_XCPU is not a KSE event,
  it's a process-wide event.  IMO there really should probably be two
  ASTPENDING flags, one for per-process, and one for per-KSE.
