Ok, your question brings me back from summer hibernation. :)
This is what I do:
- Sort the tasks in decreasing time order; the ones that will take the
most time should go first.
- Use a work unit size of 1.
The longest running task will start first. You can't get better than
that. When I print some progress reporting, I see that most of the time
N-1 tasks have finished and we are waiting for that one longest running
task.
