There already is a malloc library that does this, plus it can call
cleanup for you -- there's more to cleaning up than freeing memory. :-/

On the other hand, I wonder if the overhead when managing data
structures like that really offsets the additional work we'd need to do
otherwise, which is simply checking a few more return values.
