It would be cool if you could tell the session handler to fall back to the
default file based session handler, and preference drivers to fall back to
"none" or "php sessions" if connections to custom drivers fail.

Say you're using a DB server for prefs, and it becomes unavailable.  Rather
than say "There was a problem contacting the DB server", and preventing  it
fails back to built-in php methods and says something like "There was a
problem contacting the preferences database.  You will be using default
prefereces for the duration of this session".

Similarly, if you're using a SQL based session, if it can't connect to the
sessionhandler, rather than preventing the user from using the application,
how about throwing up a notice saying that it's using the default session
handler, and then continuing?
