From: "Artem V. Andreev" <***@oktetlabs.ru>
The manager provides a way to allocate physically and virtually
contiguous set of objects.
Note: due to the way objects are organized in the bucket manager,
the get_avail_count may return less objects than were enqueued.
That breaks the expectation of mempool and mempool_perf tests.
