Detailed Description

template<class T>
class ACE_Cached_Mem_Pool_Node< T >

ACE_Cached_Mem_Pool_Node keeps unused memory within a free list.

The length of a piece of unused memory must be greater than sizeof (void*). This makes sense because we'll waste even more memory if we keep them in a separate data structure. This class should really be placed within the ACE_Cached_Allocator class but this can't be done due to C++ compiler portability problems.

Since memory is not used when placed in a free list, we can use it to maintain the structure of free list. I was using union to hide the fact of overlapping memory usage. However, that cause problem on MSVC. So, I now turn back to hack this with casting.
