I do remember we studied Exokernel at school. The slogan "exterminate
all abstractions!" or something to that effect springs to mind. The
idea I believe is that an Exokernel should do just what is absolutely
necessary to provide protection (aka. "safe multiplexing" between
processes/applications/subsystems), and nothing in the way of
abstraction ("libraries" you might say).

I have to confess I don't immediately see how this relates to the
"busy-looping problem". Maybe you can say something more about what
you had in mind?

Thinking about it now, on a conceptual level it seems to me that
Movitz is almost the antithesis to Exokernel, as Movitz is pretty much
all abstractions an no protection.. :-)
