That is not nearly complete. The Heap a memory structure attahced to
the processor control record that has pointers to areas in the memory
which are defined ad hoc in user space and are not defined in the PCR.

I can be wrong though.

Heaps can be allorthims which are nearly complete binrary trees with
values stored at nodes.

FWIW, that is tonights class for me...
