Either XOR is need, or you need to provide an alternative way
for me to get at the same information for that function.
In verify_local_live_at_start we are expecting set A == set B,
and if they aren't equal, we need to find all the bits that
are different and validate the changes that occurred.
Removing NOT and IOR_COMPL make sense, especially if they aren't used.
