This class is used to allocate bytes of memory from a pool that is never intended to be freed. It is particularly useful to support DeletedChain, which allocates memory in just such a fashion.
When it is known that memory will not be freed, it is preferable to use this instead of the standard malloc() (or global_operator_new()) call, since this will help reduce fragmentation problems in the dynamic heap. Also, memory allocated from here will exhibit less wasted space.
Returns the total number of bytes consumed by all the pages allocated internally by this object.
Returns the total number of bytes requested by the application in calls to NeverFreeMemory::alloc().
