While I agree that OT can run without system task time, it is very
unusual and lots and lots of extra work, to write an application which
can interact with OT without system task time. Interarchy happens to be
able to do this, hardly anything else has the code needed to work without
system task time. So, as a practical matter system task time is usually
required. I am only talking about OS 9 here.

Dr. Seuss books . . . can be read and enjoyed on several levels. For
example, 'One Fish Two Fish, Red Fish Blue Fish' can be deconstructed
as a searing indictment of the narrow-minded binary counting system.
