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.
