Accessing data from the Apache request in an AuthenHandler destroys it for the content handler?

With this Apache config:

<VirtualHost modrubytest>
    DocumentRoot /var/www/test
    RubyRequire test/modrubyauthentest

    <Location />
        SetHandler ruby-object
        RubyAuthenHandler Test::ModRubyAuthenTest.instance
        RubyHandler       Test::ModRubyAuthenTest.instance

        AuthName SomeRealm
        AuthType Basic
        Require valid-user

        Options +ExecCGI
    </Location>
</VirtualHost>

and this ruby:

#!/usr/bin/ruby

require 'singleton'

module Test
    class ModRubyAuthenTest
        include Singleton
        def handler(r)
            r.content_type = 'text/html'
            if r.method_number == Apache::M_GET
                puts <<END_HTML
<html>
<body>
    <form action="/" method="post">
        <input type="hidden" name="foo" value="bar" />
        <input type="submit" />
    </form>
</body>
</html>
END_HTML
            else
                puts r.param('foo')
            end
            return Apache::OK
        end

        def authenticate(r)
            # Uncomment either or both and r.param('foo') in handler() is
nil
            #r.param('foo')
            #r.cookies
            return Apache::OK
        end
    end
end

Everything works. On GET a page comes up with the submit button, and on POST
it displays 'bar', the value of the hidden input 'foo'.  But, if I uncomment
either of the marked lines in authenticate() the output from the same action
is nil (ie, r.param('foo') is nil).  The behavior is the same without using
Singleton.  I assume this is a bug, as neither line should change any data,
but would be happy to be corrected about any misunderstanding on my part.

Thanks.
