Or perhaps the way to opt into the feature is to create an empty
file $GIT_DIR/lockfile-audit, and the lockfile subsystem will append
to it every time a lock is taken? We need to ensure that a PID and
pathname formatted into a single record is small enough and O_APPEND
would relieve us from worrying about multi writer races, which may
introduce different kind of complications, though.
