* Use the new tsc functions to poll for new read data in a pipe for a short
  period of time on a SMP box.  This greatly increases the odds of a pipe
  writer on one cpu being able to pipeline data to a reader on another cpu
  without having to use an IPI or tsleep/wakeup.

  For the pipe1 test this brings the synchronous communications path
  over a pipe (Awrite, Bread, Bwrite, Aread) down from 7uS to around 2uS.

  For the pipe2 test this value greatly reduces the number of IPIs
  and improves bandwidth by a few hundred megabytes/sec (the old DELAY
  did the same thing so there is no change for the pipe2 test).

* Add sysctl kern.pipe.delay which defaults to 5000 nanoseconds (5uS).
  This is the maximum a pipe reader will wait for additional data before
  falling back to tsleep/wakeup (and related ipis).  pipe_delay may be
  set to 0 to disable the function.  I value of at least 3000 is
  recomended.  Pipelining large buffers efficiently requires a higher value,
  say up to 8000 or so.

* Allow kern.pipe.mpsafe to be set to 2 which adds a predictive wakeup
  when a writer is found to be stalled.  This currently has no significant
  effect on operations due to token collisions.

* Add statistics: kern.pipe.wblocked and kern.pipe.rblocked, counting

vrevoke/single-user - fix more revoke issues.

* vrevoke() no longer clears vp->v_rdev.  Doing so interferes with specfs's
  ability to call dev_dclose().  Fixing this will allow the regular close
  of the vnode to close the underlying device.

  Since the revoke code detaches the vnode from any user-visible file
  descriptors the vnode will end up being closed the moment the last
  referenced to the detached fp goes away.

* kill 1 no longer leaves the syscons in a state where both /dev/ttyv0 and
  /dev/console are marked open (due to the above bug).  This state would
  cause the keyboard to stop working sometimes when dropping into single
  user.

* Add dev_drevoke() and friends.  This allows a device to do something
  when an attempt is made to revoke() the related vnode.

  TTY and PTY devices now attempt to break out of any ttysleep() operation
  (such as when processes are blocked in read()).  This is advisory and
  if it fails to break a process out of a blocked condition that process
  will still detach after the blocked condition is resolved normally.
