[ODE] About "malloc" patch

[Jon Watte]

> Shortly, why not use smart pointers?

I suggested more or less the same thing, and even provided an 
implementation on the list (not integrated to the ODE source), 
but the original submitter preferred his own method.

In my opinion, the best allocator to use would not need UNALLOC 
at all; instead, it would linearly allocate from a large block 
of memory, and re-set at the top of each Step() function. When 
the large block (that's pre-allocated) is not large enough, then 
a new block can be allocated and added to the list of allocatable 
memory. An implementation much like that was also posted to the 
list if you look in the archives (again, not integrated into the 
ODE source).

Cheers,
