Certainly that would help, and it might be an easier sell to the kernel
hackers: instead of arguing "this policy is foolish", we only have to
say "your VM accounting is wildly inaccurate". We'd still end up with a
postmaster at more risk than we'd like, but at least not at dozens of
times more risk than any backend.
