The intended usage is for recording current system statistics from /proc in buildstats.bbclass during a build and for improving the BB_DISKMON_DIRS implementation. All other existing hooks are less suitable because they trigger at unpredictable rates: too often can be handled by doing rate-limiting in the event handler, but not often enough (for example, when there is only one long-running task) cannot because the handler does not get called at all. The implementation of the new heartbeat event hooks into the cooker process event queue. The process already wakes up every 0.1s, which is often enough for the intentionally coarse 1s delay between heartbeats. That value was chosen to keep the overhead low while still being frequent enough for the intended usage. If necessary, BB_HEARTBEAT_EVENT can be set to a float specifying the delay in seconds between these heartbeat events.
