One other minor problem is that old is not the current value of z (or
new for Fractint), it is the value at the start of the iteration that
ends with bailing out.

The only time FractInt uses old is to first initialize the lastz. Isn't old at that point the initial value of z before the first iteration? The value of old at the end of iterations isnt used.
