It depends on the app, but in general I agree.

Demo/threads/ in a Python source distribution contains thread-based
implementations of coroutines and generators.  They were certainly
just demos, and PEP 255 even mentions the latter as a concrete example
of why threads aren't a practical implementation technique for
generators.
