OK, multiple runs are harmless, so I don't mind this change if it
smooths out any inconsistencies in practice.  The patch also looks OK
to me but I'd like a consolidated ouput instead of the four output
files, maybe as a separate change.  I'd like to see if anyone else has
objections to this, so please wait for another ack before you commit
it.
