Interesting idea but the tasks that I want to run have already been developed in a
stand-alone way. Wrapping them into a thread or keeping them standalone and making
them coordinate via some shared-state server wouldn't be too hard but organizing them
as you suggest sounds like it could be some work.

Could you break your task into little chunks and run it as a state machine
with a permanant process that runs state 'chunks' and records progress?
Its an odd way to do it, but it lets you run it all in a single thread.
