Huh, and what if I accidentaly mistype the number and destroy a valid
page? Maybe the command should only succeed if it confirms that the
page is corrupted.
There could also be "DESTROY ALL PAGES" and/or "DESTROY n PAGES"
commands, where the latter zeroes the first n corrupted pages in the
table, for the case with lots of corrupted pages. Maybe a command for
getting a list of the corrupted pages is useful?
