Title:
  Requests are not cleared if a client dies unexpectedly and drops from
  the bus

Status in the base for Ubuntu mobile products:
  Fix Committed
Status in PowerD:
  In Progress
Status in powerd package in Ubuntu:
  In Progress

Bug description:
  Power requests (wakelocks) are not released if the owner process
  unexpectedly exits and drops off the bus. This causes a stale request
  that holds the device awake, which can result in extreme battery
  drain.

  For example, the vibration sensor can unexpectedly die while holding a
  vibration/alarm lock and at the point the phone would never again
  suspend.
