Good idea, at least for debug versions. I think I did this myself,
although as I recall I used the hex pattern "FEED FACE DEAD BEEF" -
which I picked up way back in high school when I cut my teeth on the
IBM 1130.
You probably wouldn't want to spend the overhead on the memset() calls
in a production version.
