+JH/27 Fix SOCKS bug: an unitialized pointer was deref'd by the transport process
+ which could crash as a result. This could lead to undeliverable messages.
+
+JH/28 Logging: "next input sent too soon" now shows where input was truncated
+ for log purposes.
+
+JH/29 Fix queue_run_in_order to ignore the PID portion of the message ID. This
+ matters on fast-turnover and PID-randomising systems, which were getting
+ out-of-order delivery.
