It might allow dynamic heap size management more easily than with a
single heap.
If you really think it will be better, try it. You'll learn loads, right
or wrong. It's difficult to forecast ahead of time what's a good idea
and what's a bad idea. The real truth of these things is that you need
to pop the hood and start tinkering and its's quite hard to make a plan
for that. If you have a bad idea, just move on to the next one; they're
just ideas.
