If you are running these jobs by hand you are doing something that
will be expected to take a long time (initial sync, recovery, etc.).
Make these scripts assume interactivity and default to *not* running
under timeout -- it's too easy to forget NO_TIMEOUT when running
manually and having the job killed.
We already have an UNDER_CRON variable set so that we only send stats
when running ... under cron. Reuse this here for the timeout flag.
