    queue2: only block serialized query when it's safe

    We must be certain that we don't cause a deadlock when blocking the
serialized
    queries. One such deadlock can happen when we are buffering and downstream
is
    blocked in preroll and a serialized query arrives. Downstream will not
unblock
    (and allow our query to execute) until we complete buffering and buffering
will
    not complete until we can answer the query..
