Hi Franz,

good idea. But this could end up in hundred of mails. Think about this 
happens at the Weekend and many users call the page.

We already have the devlog extension which saves the errors in DB. Maybe 
an email has to be send if first devlog entry happens on a page.

My first intention also was for the user, maybe page_unavailableHandler 
should be called in such case?
