Well said, especially the last line :)

However, I suspect this is one of those things where:
- rewriting it yourself is easier than finding a library for it, so a
PyPI module would gather little interest or feedback
- doing it "right" in the stdlib would eliminate the temptation to
develop custom not-quite-right implementations (e.g. ones where the
decorator actually *creates* and starts the thread)

It would make a good topic for a PEP, IMO.
