------------------
JH/01 Use fewer forks & execs for sending many messages to a single host.
- By passing back the next message-id from the transport to the delivery
- process, we can loop there. A two-phase queue run will benefit,
- particularly for mailinglist and smarthost cases.

JH/02 Add transaction support for hintsdbs. The sole initial provider is
- sqlite, and is used for the wait-trasnprot DB. Transactions imply
- locking internal to the DB. We no longer need a separate lockfile, can
- keep the DB handle open for extended periods, and still potentially
- benefit from concurrency on non-conlicting record uses.
