Detailed Description

template<typename _Tp, typename _Poolp = __common_pool_policy<__pool, true >>

class __gnu_cxx::__mt_alloc< _Tp, _Poolp >" This is a fixed size (power of 2) allocator which - when compiled with thread support - will maintain one freelist per size per thread plus a global one. Steps are taken to limit the per thread freelist sizes (by returning excess back to the global list).
