Public bug reported:
Since VibratePattern calls can't be cancelled, clients that need to be
able to end a loop abruptly have to manage the loop on their own and
call VibratePattern with a repeat count of 1.
Use case: a wakeup alarm notification should be accompanied by haptic
feedback which should stop when the notification is dismissed.
Calling VibratePattern() with a count to repeat indefinitely would be
better for bus traffic, but is impossible because the repeating
vibration would continue after the user's dismissed the alarm.

- There's currently no way to cancel a repeating VibratePattern calll, so
- clients that need to be able to end a loop abruptly have to manage the
- loop on their own and call VibratePattern with a repeat count of 1.
+ Since VibratePattern calls can't be cancelled, clients that need to be
+ able to end a loop abruptly have to manage the loop on their own and
+ call VibratePattern with a repeat count of 1.
- Use case: there should be haptic feedback when displaying a wakeup alarm
- to the user, but the vibrations should stop once the user dismisses the
- alarm. Calling VibratePattern() with a long repeat count would reduce
- bus traffic, but is impossible because the repeating vibration would
- continue even after the user dismissed the alarm.
