Need a worklist generator as an alternative to actually performing the work

[haxsaw]

The worklist generator should be able to intercept actions (tasks) and record somewhere the work that would need to be done to actually perform the task. The tricky part of this is to somehow convey where you include data from a previous task in the input of a new task. This should go into a file in a format that suitably represents the parallelism in the work.
