	* The root of cached pages pool is protected by both the per-object lock
	* and the free pages queue mutex.
	* On insert in the cache radix trie, the per-object lock is expected
	* to be already held and the free pages queue mutex will be
	* acquired during the operation too.
	* On remove and lookup from the cache radix trie, only the free
	* pages queue mutex is expected to be locked.
	* These rules allow for reliably checking for the presence of cached
	* pages with only the per-object lock held, thereby reducing contention
	* for the free pages queue mutex.
