It's the only way to avoid a core dump when the system tries to process
the page. And no, I don't want to propagate the notion that "this page
is broken" beyond the buffer manager, so testing elsewhere isn't an
acceptable answer.
Basically, one should only turn this variable on after giving up on the
possibility of getting any data out of the broken page itself. It would
be folly to run with it turned on as a normal setting.
