  * DESCRIPTION: Invoked directly from the SCI handler when a global lock
- *              release interrupt occurs. Attempt to acquire the global lock,
- *              if successful, signal the thread waiting for the lock.
+ *              release interrupt occurs.  If there's a thread waiting for
+ *              the global lock, signal it.
  *
  * NOTE: Assumes that the semaphore can be signaled from interrupt level. If
  * this is not possible for some reason, a separate thread will have to be
  * scheduled to do this.
