What I don't like is the idea that the GC will have to go through ALL
data memory (and registers) looking for pointers. The time it takes
to make a scan is proportional to total memory size rather than proportional
to the number of pointers in use, or proportional to the number of
heap blocks, or proportional to some other reasonable value.
