That is not "ideal", in fact it would break one of the specific features
that UUNET asked us for. Namely, to be able to have noninterfering
sets of socket files in different explicitly-specified directories.
If the lock files don't live where the sockets do, then this doesn't work.

We aren't counting on data to be stored in /tmp "between invocations".
The socket and lock file live only as long as the postmaster runs.
