To embellish the structure it could be renamed to:
struct
{
        pool data, heap, stack;
} process;

Where the default implementation of the global operator ::new could be:
void * operator new(size_t n) { return ::process.heap.malloc(n); }

If you call is_from() with a pointer p then pointer p is guaranteed to 
be part of one of the pools mentioned above.
