Comment (by olly):

 So some experimental hacking later, I have a hand-modified version which
 works for Python and VRPs.

 To make this work we need to call `vrproc.__disown__()` just ''after'' we
 call the C++ `add_valuerangeprocessor()` method, **and** we need to
 `unref()` the C++ vrp object then too (otherwise both the C++ and Python
 objects will end up with one reference and neither will get deleted),
 **but** we need to only do this if the object hasn't already been
 disowned.

 This is going to need a bit of work to get it to happen, but at least we
 now have a plan.
