drainTo provides the capability for a "bulk poll" operation which is only
needed in a concurrently accessed queue. Queue is not specified for
concurrent use while BlockingQueue is.

It would be possible to have a concurrent implementation of Queue that
chooses not to also be a BlockingQueue, and which might also want a drainTo
