Comment(by richard):

 With the latest swig, most of the DeprecationWarnings disappear: running
 the testsuite now only produces two.  I've tracked their source down, and
 both come from
 the SWIG_Python_NewShadowInstance() function, where it calls
 """PyBaseObject_Type.tp_new""" (ie, calls the __new__ method on the base
 "object" object).  According to http://bugs.python.org/issue1683368 since
 2.6 passing any arguments to object.__new__() gives a warning (see
 http://www.python.org/download/releases/2.6/NEWS.txt and search for
 1683368).  The warning won't happen with 2.6 because SWIG only uses that
 code for python 3.0 or later.

 I think we could stop the warning by stopping passing args to tp_new(),
 but then we wouldn't be using the args at all.  I'm not quite sure what
 this code is trying to do, but I'm sure it's meant to use the args
 supplied to it!
