One easy project is to support memory managed RTLinux tasks. This
was the original design and we dropped it for performance reasons and
when modules started working well. But it should be relatively easy to
take a 4Meg chunk of memory, reserve it for RTLinux modules, make
a map for it, and then fix the rtscheduler to really switch.
