System specific libraries can supply modules that override common (machine
independent) modules. This feature is used for GEOS and may be used for the
NES to handle the special placement of the heap. I try to avoid it when
possible, but there are situations where this is useful, and - assuming the
coprocessor is a lot faster than the main CPU - this is such a situation.
