ActionScheduler_QueueRunner::clear_caches()protectedWC 1.0

Flush the cache if possible (intended for use after a batch of actions has been processed).

This is useful because running large batches can eat up memory and because invalid data can accrue in the runtime cache, which may lead to unexpected results.
