Yes, please :) it would be super.
We should not have that ".SendResponse" line at all in our event 
handlers, just like with CGI and Apache modules with fpweb.

Handled := true; should only be checked after the event handler 
finished, as an indicator that the request was handled and the response 
was generated and can be found in the ".Content" .
What is the purpose of the Handled parameter if not this with 
cgi/fcgi/apache_module?
