Theoretically, you are right. Practically, you need first to clean that
memory (i.e., not have malloc-ed blocks there), otherwise it would just
drop dead. Given that standard malloc/free combo doesn't give you _any_
control on where blocks are allocated, you'll have hard time freeing top
of your heep unless you free totally everything. If you really need that,
use custom allocator.
