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.

This is very interesting Jason. We still do some work in OS/9. I would
love to know what is required to get OT to work without SystemTask time.
Is there a technote or example for reference? This would be very
interesting to know.

Just a quick clarification. While you may be able to write your code so you can get everything you need done without system task time, OT does rely on system task time to grow it's memory pools. If you run on Mac OS 9 for a long time without yielding time by calling WaitNextEvent or any of the other various methods, you can starve OT of system task time and cut OT off from memory it may desperately need. A common operation that can lead to this is saving a very large file to a network file system.
