 * This handles collecting memory when OOM occurs, by clearing the cache.

 * The StopScheduler has two collection modes, low and middle priority.

 * When memory is at a certain threshold, all collectors low and above are called.

 * When memory is at a critical threshold, all collectors middle and above are called.

 * We want the cache to always clear whenever OOM happens so this collector's
