The fact that RLock's *appeared* to be picklable was a bug in previous versions of python (see issue 22995).

If you had code that worked before actually using the locks then perhaps there is a deeper error, though, so I'm nosying Serhiy to take a look at this (I don't use concurrent.futures so I'm not qualified to evaluate your example for validity).
