In my mind the main reason die() exists is to kill individual 
backends which seems to be in trouble without causing
the database-wide restart.
Before 7.1 QueryCancel flag was checked at the points
CHECK_FOR_INTERRUPTS are currently placed.
But the QueryCancel flag had nothing to do with die
interrupts.
