Retire "Active reparenting" After 6K games at 60" + 0.1 on QUAD with 4 threads this implementation fails to show a measurable increase, result is well within error bar. Perhaps with 8 or more threads resut is better but we don't have the hardware to test. So retire for now and in case re-add in the future if it proves good on big machines. The only good news is that we don't have a regression and implementation is stable and bug-free, so could be reused somewhere in the future. No functional change.
