topological sort only works if you assume
that each task is completed before the next
one starts. To run tasks in parallel you
have to maintain a queue of tasks that are
ready to run and add tasks to it as their
dependencies complete. It isn't terribly
difficult, but it's more complex than a
straight topological sort.
