      Thinking about this a bit more, I'm not sure of the usefulness of
      checking content-length at this stage - it may be too late.

      What's the motivation? To stop deliberate attempts to overload/crash
      the SOAP application? By the time the CGI application runs, the http
      server has probably read all the request anyway. Maybe it's the http
      server which needs to have limit applied?

      However I notice that CGI.pm has a similar idea, $CGI::POST_MAX,
      so perhaps it's a sound idea.
