It's a good goal. You can reduce the likelihood of failure

Not true. You can prevent fragmentation, for example, by
not allocating objects beside each other that will be destroyed
at different times. Or, you can pick a
The only real way to prevent allocation fragmentation is to move
blocks of memory around - i.e., return and manilpulate handles to
pointers instead of the pointers themselves. But this adds a lot
of runtime overhead and is not C friendly.
Anything else is just a compromise. Predictive and

Interesting paper. Thanks for the
Hi Richard,
This might be worth a read. This paper discusses limitations of custom
memory allocators:
