> PathChildrenCache currently takes an Executor, but only to fire off a
> Runnable that does a blocking while loop waiting for work. This means that
> you must have one thread per PathChildrenCache, which is not that great.
> PathChildrenCache should just use the Executor's work queuing mechanism to
> enqueue work items instead of maintaining its own work queue mechanism.
