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.
