NOR "bad blocks"

just a thought...
Same as NAND, NOR flashes mostly have an endurance of guaranted 100K
If a block reaches this (theoretical) value, it should be recognized as
bad block if erase fails; e.g. not conaining only 0xFF after erase on
NAND. (I don't know if the "100K" erase cycle boundary is mostly
responsible for this)
But obviously a block can wear out on NOR too after the max. number of
erase cycles. (How) can this be recognized, handled?
