    Yes, running one scheduler on top of Exec it not a casual concept
to implement!  I tried putting a VAX/VMS like scheduler on top of
Exec's scheduling and had nothing but trouble.  The system was the
Wendin Operating System Toolbox. <--REFERENCE  Although I did get it
to work, the evil I was performing would make Carl lose sleep and
pace the floor.  One thing missing from the Exec process state
is "SUSPENDED": don't even try to launch me.  I faked it by
just placing the task on the WaitList.  I believe if you blew off
DOS, that creating the task would be much easier, though.
