.SH "Detailed Description"
.PP 
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)\&.
.PP
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\&.
