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. Definition at line 74 of file pool_allocator.h.
