Why? You could say same thing about disks: If disk failures mean your users 
cant login, then you're using disk incorrectly. 

session data dont needs to be saved to disk, they just needs to be store and 
retrieved quickly and more important to me: distributed for a bunch of 
webservers. before i used a postgresql instance to save session data but it 
turns out to become a bottleneck by itself (not because of postgresql of 
course but an rdbms is overkill to session data imho)

I don't like installing new version all the time before i didn't understand 
the problem and i like using debian stable software as it is updated if 
security concerns exists.
