Thanks to Bernd and everyone else who has responded.  Unless someone
reports a case where the old "optimization" gets applied more often
than 1 in ten million copy-on-write faults, I'm going to remove
the old code in a few days.  At this frequency, the cost of deciding
whether or not to apply the optimization on every copy-on-write fault
is greater than what is saved those 26 times it is applied.
