It is a nice idea, however I understand everybody needs are not the same.

Regarding my application, I setup dynamically my heap once. But this 
heap size depends will depend on some external parameters and will vary. 
And the only way to know the size to allocate is to "count" the 
databytes in my C programing structures. Honestly, I am sure a computer
will better do it than my mind.

eg. These external parameters may depend on how many motors in my 
machine, and so on.
