Hum, this implies that flash messages are shown at the end of the script 
processing, before the request ends. Is it always the case?

Isn't it possible _yet_ that a request prepares flash messages that are 
shown with another HTTP request? I guess if we use an ExtJS-based 
module, we will have actions that are asynchronous and that push Flash 
messages while another process (with AJAX) fetches those Flash messages 
and show them. Without a DB or storing them in the session (would be 
quicker than DB I guess), how is a static variable supposed to work when 
PHP is stateless?
