The idea is that any non blocking call is an opportunity to switch
between greenlets. The monkey patching system will enable this.

If you don't have any place in your greenlets that are monkey patched
(and therefore allow switching), you can be a good citizen and drop in a
patched sleep call so that other greenlets will get time to
run. Otherwise, you'll simply hog the interpreter and no one else will
be able to run.

This the principle. I still don't understand your question.
