What is new?

1. Lock-free free list.
2. Provide both region allocators (boost::auto_alloc, boost::scoped_alloc)
and general-purpose allocators


1. Allocating memory is very fast.
2. No memory leaks. No need to delete objects manually. Or forgetting to
delete objects is allowed.

What is boost-memory?
It provides allocators named "GC Allocator". Note "GC Allocator" isn't GC.
GC Allocator is different from STL Allocator. The following is minimum
specification for GC Allocator:
typedef void (*DestructorType)(void* data);
concept GCAllocator
    // Allocate memory without given a cleanup function
    void* allocate(size_t cb);
    // Allocate memory with a cleanup function
    void* allocate(size_t cb, DestructorType fn);
    // Cleanup and deallocate all allocated memory by this GC Allocator
    void clear();
    // Swap two GCAllocator instances
    void swap(GCAllocator& o);
