But the class being passed to isinstance() can only be
a proxy to the remote class as well, so as long as it's
the same proxy that the overridden __class__ returns,
it should work, shouldn't it?


   in process A:

         x.__class__ is X


         isinstance(x, X) == True

   in process B:

         x_proxy.__class__ is X_proxy


         isinstance(x_proxy, X_proxy) == True
