Detailed Description

PageArena memory allocator.

This class efficiently allocates memory chunks from large memory pages. This reduces the number of heap allocations, thus causing less heap fragmentation and higher performance. The PageArena memory allocator can not be used for STL classes - use PageArenaAllocator instead.
