It is the responsibility of the virtualhost housekeeper (see
VirtualHostHouseKeepingTask and
org.apache.qpid.server.queue.AbstractQueue#checkMessageStatus).  The
period with which the housekeeper runs is defined by
virtualhost.housekeepingCheckPeriod so a message may remain held of
the queue by virtualhost.housekeepingCheckPeriod ms too long.
