Right, that's what I gleaned from skimming the referenced paper. But
that and the lwn article you link only show C code. Let's see some
Python! (I would try it, but no machine I have access to supports this
yet.)

Hopefully the OP has some sample Python code? Otherwise I think it's a
little too early to adopt this...
