No, I agree with you there. I appreciate your attempt, and it would have
been great if it had worked. My comments are only about going forward
from today onward. And, going forward, I don't believe that this API
simplification (and regression in functionality) is going to pay off
the way you'd hoped.

Ok, not you then :)
I'm willing to do it, but since I won't be able to spend full time
reviewing it, I'd have to set some ground-rules, like: I"ll pull in
any patch as soon as it has an ack from (Oren, Dan Smith, Matt
Helsley) which is not also from the submitter. Any regression in
automated tests cause the patch which caused it to get kicked out.
If you want to discuss the technical advantages of not allowing a task
to call checkpoint on another task, let's start a new thread to do that.
So far, I'm against it.
thanks,
