... the above hunk caught my eye. I don't know that it matters that
much, but since you have reordered parameters on some functions, should
pp->get_next_task() take the 'task_cb' as the last parameter, rather than
the first?
I have not looked at the final result yet (just the interdiff), so please
just ignore the above if I've missed something obvious. :-D
