But presumably you want OTHER modules to continue using the vanilla
threading module? This is likely to end up somewhat hacky. Yes, you
can manipulate sys.modules, but there's only one threading module at a
time, so you need a way to distinguish between modules that should use
the changed one and modules that shouldn't.

TBH this is starting to sound like something where you want
unittest-type facilities, actually.
