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.
