Agreed.

Yeah, it should primarily be used as a Condition method. I was
suggesting implementing that Condition method in terms of a threading
function, which would also help other people trying to, say, mock
Condition objects. But that's not a big deal, and I could be wrong
about whether it's useful at all. As I said earlier, I'm happy with
this patch either way. (Note that Condition.wait_for is helpful to
people mocking Condition anyway, since the number of calls is much
more fixed than the calls to Condition.wait.)
