Detailed Description

       Base class for __pool_alloc.

       Uses various allocators to fulfill underlying requests (and makes as few requests as possible when in
       default high-speed pool mode).

       Important implementation properties: 0. If globally mandated, then allocate objects from new 1. If the
       clients request an object of size > _S_max_bytes, the resulting object will be obtained directly from new
       2. In all other cases, we allocate an object of size exactly _S_round_up(requested_size). Thus the client
       has enough size information that we can return the object to the proper free list without permanently
       losing part of the object.
