From v0.9, AcquiredTask#timeout stores the time when it is acquired. This commit changes the semantics to the last heartbeated time.
* Avoid to touch created_at because it is misused and maybe used in different meanings in the future. From v0.8.48, PQ can use timeout to find living tasks. * Check timeout on heartbeat. v0.9's AcquiredTask#timeout saves the last heartbeated time. PQ can check whether the heartbeating task is still acquired by itself or not.
pass thread execution until monitor thread send heartbeat (or wait while current alive time is available) and sleep for next heartbeat.
To confirm task is alive, wait task_heartbeat in set_task.
I thought timeout's meaning is changed in v0.9, now I can change its type.

There was a problem hiding this comment.
Looks like that assigning task is unnecessary.
On prefetch, Processor keeps when it acquires the task.
