I worked this out - the following code in my parser's __init__ does the job:

        self.count = getattr(request, 'Parser_counter_Count', 0)
        request.Parser_counter_Count = self.count + 1

What was going wrong in my earlier tests was that I was using a name
starting with __ and Python mangles the name in that case (in the
second line, but not in the first).
