I've used JMH to perform the burst tests (ie drainInBurst, pollInBurst) and
an unbounded offer/offerFirst (with pure accumulation, to kill any GC, using a
huge heap).

As can be seen ChunkedQueue performs for fixed sized bursty scenarios like
an ArrayDeque (ie 1 order of magnitude better than any linked list) and for
accumulating burst (with no consume involved) one order of magnitude better
than a linked list (artemis or the Java Collection one).
