It might be useful to allow a custom malloc/calloc/realloc/free and 
new/delete/new[]/delete[] implementation to have a possibility to trace 
memory allocation. But on the other hand were is this really needed? For 
leak checks it might be helpful, if we would keep a list of blocks etc. 
which can be shown if requested (maybe always at program termination). 
Apart I do not see too much use of it.

Actually in an C++ program you should try to avoid malloc and free, 
since they never call constructors for classes for example. But that is 
a different story I suppose... :-).
