/**
* Scaffolding for implementing robust background processing scripts.
*
*
* Autoscaling
* ===========
*
* Autoscaling automatically launches copies of a daemon when it is busy
* (scaling the pool up) and stops them when they're idle (scaling the pool
* down). This is appropriate for daemons which perform highly parallelizable
* work.
*
* To make a daemon support autoscaling, the implementation should look
* something like this:
*
* while (!$this->shouldExit()) {
* if (work_available()) {
* $this->willBeginWork();
* do_work();
* $this->sleep(0);
* } else {
* $this->willBeginIdle();
* $this->sleep(1);
* }
* }
*
* In particular, call @{method:willBeginWork} before becoming busy, and
* @{method:willBeginIdle} when no work is available. If the daemon is launched
* into an autoscale pool, this will cause the pool to automatically scale up
* when busy and down when idle.
*
* See @{class:PhutilHighIntensityIntervalDaemon} for an example of a simple
* autoscaling daemon.
*
* Launching a daemon which does not make these callbacks into an autoscale
* pool will have no effect.
*
