Try shutting down the session by calling session_write_close() before
you call ini_set(). The update handler on session.save_handler checks
the session status. Resetting the status to inactive should allow you
to have the handler back to "files."

I wonder how well such a fallback mechanism would work. Active sessions
at the moment when the database goes down would be lost. The same thing
would happen when the database comes back online as the session files
are now ignored.
