AFAICT, it is possible to arrange things in Coyotos so that (say) things
don't get swapped to disk and that memory is always available for the
services that need it.  There were various discussions about this to do
with windowing systems; for example, you want to know that you'll always
be able to bring up a "task manager" to kill off offending processes,
hence a way of reserving the appropriate resources for this in advance
is needed.  This example involves quite complicated interactions between
lots of different services needed to do its work and arranging all this
is somewhat difficult.
