Just don't access the same data? Threads, greenlets, tasklets, etc. allow you to share state, but don't force you to. Greenlets/tasklets are game changing with respect to OS threads not because they introduce new ways of working, but because their performance and scalability afford you ways of working that would be theoretically possible but impractical with threads. The GIL only widens that gap.
