(1) Because we're not really interested in supporting multiple fundamentally
different approaches to postmaster interlocking.  The system is
complicated enough already.

(2) Because according to discussion so far, we can't rely on this "solution"
anywhere.  Postgres can't easily tell whether its data directory is
mounted over NFS, for example.
