  13.9  SYS$RELEASE_GALAXY_LOCK

  This service releases ownership of a galaxy lock.  Because
  a galaxy lock can be acquired multiple times by the same
  owner (nested ownership), the lock is not released until the
  ownership count goes to zero.  If the lock ownership is com-
  pletely released and there are other threads waiting for the
  lock, they are released from their wait states.
