It was a suggestion I gave to the GSOC student. The intention was to try 
and avoid adding and documenting a whole new manager which would end up 
looking very similar to the existing one.

I hope we follow the score model of an internal API and then a mapping 
to the Classic API. This way we can support functionality in the score 
such as a single alloc for the TCB+stack and it being private to a task.
