They needed something to fill up a bunch of space. The three obvious choices
are nulls, a fixed pattern, and random bits.
Nulls could be "sparse"-ized down in some filesystems, causing problems down
the line.
Random bits have the problem that it can be very difficult to figure out, a
posteriori, where you have and haven't overwritten anything.
So you pick a pattern, and do it lots. Eric got to pick. :)
