$POST_MAX flag that forces the server to return a fault if a request exceeds a user-defined number of bytes. This is a hack, in anticipation of similar support being added to the core SOAP::Lite package. I haven't looked at the XMLRPC::Lite stuff yet, but I'm guessing that adding similar support is only a question of exporting a $TRANSPORT package global and making sure to return the right kind of error widget.
