True virtual memory must be imbedded in the OS to be effective. According
to rumor, the "hooks" for a VM system are in AmigaDOS 2.0, just as they
are in the as-yet-unreleased Version & MACII OS. However, implimenting
a disk based blocking system for software which uses stack based data (such
as a scanline renderer) are quite easy to impliment on the Amiga with
current hardware/software.
