-// ProtectedMemoryAllocator
-//
-// A very simple allocator class which allows allocation, but not deallocation.
-// The allocations can be made read-only with the Protect() method.
-// This class is NOT useful as a general-purpose memory allocation system,
-// since it does not allow deallocation. It is useful to use for a group
-// of allocations which are created in the same time-frame and destroyed
-// in the same time-frame. It is useful for making allocations of memory
-// which will not need to change often once initialized. This memory can then
-// be protected from memory smashers by calling the Protect() method.
