There is not much "suds" can do with regard to this. In principle,
it could write to a temporary file - but its purpose is to present
the webservice result as a collection of Python objects - and
they, too, require memory in the same order.

Thus, you have the following options:

  *  learn how to limit the amount of data, the webservice provides
  *  give your system (its processes) more memory
  *  do not use "suds" but process the incoming data incrementally
     (avoiding the build of the intermediate collection of Python objects).
