There ought to be a page WP:Life is short.  The heat death of the universe may be a 10^100 Trillion years in the future... but my own personal death could happen tomorrow.  A car crash, a bolt from the blue, having a plane on appraoch to O'Hare crash into my house, who knows?  The same goes for any human being.  (Think of how many people have died sudden and natural deaths from some congenital and undetected heart defect.)  So as far as I am concerned if a process like mediation is stalled because one or more parties involved are on a wikibreak then that process is effectively dead.

I also refuse to endure another week of Dicklyon's little remarks while we wait some more for a mediator to mediate us to what I am more and more confident will only be an intractible deadlock.
