  Modified:    sys/i386/isa  clock.c
  Log:
  Major cleanup of the timerX_{acquire,release} stuff.  In particular,
  make it more intelligible, improve the partially bogus locking, and
  allow for a ``quick re-acquiration'' from a pending release of timer 0
  that happened ``recently'', so it was not processed yet by clkintr().
  This latter modification now finally allows to play XBoing over
  pcaudio without losing sounds or getting complaints. ;-)  (XBoing
  opens/writes/closes the sound device all over the day.)
  
  Correct locking for sysbeep().
