Sounds good. Now, who would like to provide a second opinion?
BTW, as far as intended purpose of the task scheduler... I can see how the
current system 'could' be used in ways that the proposed could not. Ex: The
current system 'could' service one high priority task after another until
all high priority tasks go to a WAITING state... then move down the priority
chain.. This would give tasks of equal priority, equal servicing. (the
proposed system would not be able to accomodate this as easily) However,
the current system doesn't do that. It services the first high priority
process over and over until it enters a wait state; then moves on.
This could be moot depending on the changes proposed by the dat4 group.

Certainly. I was trying to bring up their document yesterday, but had some
trouble getting the ps viewer for windows, etc... then ran out of time. I
will take a look at it.

One last thing; I have begun looking at adding a wait_multiple to
compliment the wait_event handler. This would allow wait_event(s) to
timeout, or allow for more flexibility in complicated multitasking programs.
I will try to keep focus on the TODOs for this release though 8-)
