    Description

      The PtrQueueSet class presently contains an embedded free-list-based BufferNode allocator. This mechanism supports deferring from one PtrQueue to another for allocation, so that all PtrQueueSets of a given kind can share a single allocator. A much simpler approach would be to have a separate BufferNode allocator class, which can be shared by multiple PtrQueueSets.
