That's pretty easy. We'd have to replace the registration call that
puts the Xapian VRP object into the Xapian QueryParser, something
like:

----------------------------------------------------------------------
real_add_valuerangeprocessor = QueryParser.add_valuerangeprocessor
def intercept_add_valuerangeprocessor(self, vrproc):
    self._vrps.append(vrproc)
    real_add_valuerangeprocessor(self, vrproc)
QueryParser._vrps = []
QueryParser.add_valuerangeprocessor = intercept_add_valuerangeprocessor
----------------------------------------------------------------------

in python/extra.i should do it (untested). Of course, there are other
similar situations :-/
