Thinking about dm_malloc() ... if it's entirely different, the semantics can be 
adjusted too ... say to "int dm_malloc(void **ptr, size_t size);":

- return int: error code
- **ptr: pointer to allocated memory, that way we can possibly implement pointer 
tracking (of course that'd need more work, might be a debug feature)
- size: size of allocated area

Of course that'd need -- in case you'd copy pointers -- another function to do 
so. etc etc.

off and out.
