The current trunk should be safe to restart during activity as i have put fixes in there to help make a clean stop and to ensure startup race conditions are avoided.

The only real safe method though is to have target tell initiators to log-off, wait until they log-off, force those that don't and then stop cleanly, and start up without race conditions.

We currently don't ask/wait initiators to log off, but i have plans to implement that. Also, i am unsure the initiators would be able to recover from that without manual intervention.
