Or is this a special kind of lock that you can "assert isn't locked" without locking it for yourself, and INCREF/DECREF does so?

I don't think that would work. It might be unlocked at the moment you test it, but someone might lock it between then and the following INCREF/DECREF.

Locking is like pregnancy -- you can't have just a little bit of it. :-)
