I'll add, which was a work-in-progress that implements a minor variation of most everything I typed about.  If nothing else, its _find_cycle is useful as a non-recursive linear-time cycle finder (recursion is deadly here because recursive depth-first search can easily "blow the stack" on larger graphs).

There's also "if 1:"/"else:" blocks that set up parallel cases, using threads or processes, and two ways of managing the parallelism (the one I showed before, and a more elaborate one that puts an upper bound on how large the queues can grow - which is sometimes "a problem" for multiprocessing.queue).
