 The simplest way to create and return a PSGI-compatible coderef. Pass in
 arguments to a hashref just as would to new. This returns a PSGI-compatible
 coderef, using L<CGI:::PSGI> as the query object. To use a different query
-object, construct your own object using C<< run_as_psgi() >>, as shown below.
+object, you have to construct your own object using C<< run_as_psgi() >>, 
+as shown below, because C<< psgi_app >> creates a new CGI::PSGI object
+unconditionally on every request and therefore overrides a own query object.
 
 It's possible that we'll change from CGI::PSGI to a different-but-compatible
 query object for PSGI support in the future, perhaps if CGI.pm adds native
 PSGI support.
