Speaking Name: suspend_backoff

Rationale: suspend_backoff is triggered whenever there's a rapid succession of sleep-wakeup-sleep transitions in a short period of time (10 occurrences within x ms IIRC). When that happens, SB makes sure the device is continuously awake for a bit instead of alternating a lot. The KWL count indicator could give a hint about the source of those continuous wakes, but not a definite answer because it doesn't show their time distribution.

• In relation with Wifi turning on/off when the screen goes on/off
• Too many alarms in short time may also trigger SUSPEND_BACKOFF. For instance, I had com.google.android.gms fireing several times per minute!
