I have been out of the loop for quite a while but my strongly held 
belief is that such scrubbing would be an enormous (and intolerable) 
overhead in any but a classified system running up around "secret" or 
higher. (I know of a system in Silicon Valley where they would bring us 
core dumps to print because their system was down so hard.

The dump program would take about a third of a box of fanfold and stack 
it, still blank, as I recall, in the stacker.

Seems like the law of the land was "If you did not set the value, you 
can make no assumptions about it."
