Hi Thomas,
 
please revert this! I need it to run hook render_page more than once. It is better that the programmer takes care not to run into endless loops by "die" or "exit". 2 of my plugins stopped working (captcha, terms) and I don't have an idea
how to do it in another style. Reason: to change the action only works in authenticated state. These plugins hooks in non authenticated state by render_page.
