Two root causes of the May 31 19:30 hang (orchestrator stuck for 45min):
1. /etc/rc.d/rc.docker restart had no timeout — on a host with many
containers, stopping them all before daemon restart can take 30+
minutes. Added timeout 180 so it's bounded.
2. WATCHDOG_DAEMON_RESTART_WAIT=900 (15min sleep after restart) —
unnecessary. The daemon itself comes up in seconds; containers are
handled by subsequent docker_watchdog cycles. Reduced to 90s in
master.conf, cutting worst-case orchestrator block from 45min to ~5min.
