Yeah, unfortunately the only implementation technique I have to offer right now is to turn all acquire calls internally into a loop around an acquire call with a timeout in the order of 1 second, and to check signals each time around the loop. :-(
The problem with this is that you really start tying yourself in knots. If you do a time.sleep() for one second, that can't be interrupted for a full second, either on keyboard interrupt or on releasing the lock. The finer-grained you go on time.sleep(), the more overhead you consume, and the coarser-grained you go, the more you limit throughput.
I'm not aware of any good cross-platform technique for managing thread
