"Discard" could be misinterpreted too, no doubt. None of these words
have one single exact meaning, so I have only limited patience for
this sort of argumentation.
(As for initdb's "--clobber-cache", I'm assuming we'd rename that to
match whatever we come up with here. It is what it is now only because
I was unwilling to call it "--use-debug-invalidate-system-caches-always".)
