     * 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.
     * <p>
     * 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).
     * <p>
     * <b>Non blocking behavior</b>
     * <p>
     * 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).
     * <p>
     * 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).
     * <p>
     * <b>Blocking behavior</b>
     * <p>
     * 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.
     * <p>
     * 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.
     * <p>
     * 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.
     * <p>
     * The timeout argument is interpreted as an integer value. A timeout of zero means instead to
     * block forever.
     * <p>
     * <b>Multiple clients blocking for the same keys</b>
     * <p>
     * Multiple clients can block for the same key. They are put into a queue, so the first to be

     * <p>
     * <b>blocking POP inside a MULTI/EXEC transaction</b>
     * <p>
     * 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).
     * <p>
     * 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
