It is worth noting that on modern Macs anyway, the block handler 
fires far too often for this purpose. That is we found that updating 
each time you hit the block handler is inefficient as you end up 
updating far too often. The generic rootless code instead ensures 
that a sufficient amount of time has passed before doing another 
update of all the damaged regions.
