/**
* BLPOP (and BRPOP) is a blocking list pop primitive. You can see this commands as blocking
* versions of LPOP and RPOP able to block if the specified keys don't exist or contain empty
* lists.
*
* The following is a description of the exact semantic. We describe BLPOP but the two commands
* are identical, the only difference is that BLPOP pops the element from the left (head) of the
* list, and BRPOP pops from the right (tail).
*
* Non blocking behavior
*
* When BLPOP is called, if at least one of the specified keys contain a non empty list, an
* element is popped from the head of the list and returned to the caller together with the name
* of the key (BLPOP returns a two elements array, the first element is the key, the second the
* popped value).
*
* Keys are scanned from left to right, so for instance if you issue BLPOP list1 list2 list3 0
* against a dataset where list1 does not exist but list2 and list3 contain non empty lists, BLPOP
* guarantees to return an element from the list stored at list2 (since it is the first non empty
* list starting from the left).
*
* Blocking behavior
*
* If none of the specified keys exist or contain non empty lists, BLPOP blocks until some other
* client performs a LPUSH or an RPUSH operation against one of the lists.
*
* Once new data is present on one of the lists, the client finally returns with the name of the
* key unblocking it and the popped value.
*
* When blocking, if a non-zero timeout is specified, the client will unblock returning a nil
* special value if the specified amount of seconds passed without a push operation against at
* least one of the specified keys.
*
* The timeout argument is interpreted as an integer value. A timeout of zero means instead to
* block forever.
*
* Multiple clients blocking for the same keys
*
* Multiple clients can block for the same key. They are put into a queue, so the first to be
* served will be the one that started to wait earlier, in a first-blpopping first-served fashion.
*
* blocking POP inside a MULTI/EXEC transaction
*
* BLPOP and BRPOP can be used with pipelining (sending multiple commands and reading the replies
* in batch), but it does not make sense to use BLPOP or BRPOP inside a MULTI/EXEC block (a Redis
* transaction).
*
* The behavior of BLPOP inside MULTI/EXEC when the list is empty is to return a multi-bulk nil
* reply, exactly what happens when the timeout is reached. If you like science fiction, think at
* it like if inside MULTI/EXEC the time will flow at infinite speed :)
*
* Time complexity: O(1)
* @param timeout
* @param keys
* @return BLPOP returns a two-elements array via a multi bulk reply in order to return both the
* unblocking key and the popped value.
*
* When a non-zero timeout is specified, and the BLPOP operation timed out, the return
* value is a nil multi bulk reply. Most client values will return false or nil
* accordingly to the programming language used.
