This really is an interested thread... but why do you want to scrub free
blocks?
I can think of a few reasons:
1) You're running Linux in a virtual machine. Zeroing all free space
makes it easier to compress the image file.
2) You've been looking at something "bad" and want to make sure all
traces of it are gone before the lawyers/cops arrive.
There are probably other good reasons, but I'm stalled out here.
