Detailed Description

Make a ``lighter-weight'' memory pool based ACE_Mem_Map.

This implementation allows memory to be shared between processes. However, unlike the ACE_MMAP_Memory_Pool the methods are no-ops, which means that we don't pay for the price of flushing the memory to the backing store on every update. Naturally, this trades off increased performance for less reliability if the machine crashes.
