I have believed for some time that it is important that Israel finish the security fence as quickly as possible. In the Middle East, nothing succeeds like facts on the ground. And while we'd all like to have the chance to say a Shehecheyanu as quickly as possible, Arafat might help Israel most by recovering. After the succession struggle has already started, of course.
Whether or not the circling vultures would let that happen is another story. Certainly those with the greatest interest in seeing him linger would also be those in the worst position to see that it happened.
