pub const STOP_TIMEOUT: Duration;Expand description
How long a daemon is given to exit after it accepts a stop.
Stopping cancels a token and returns immediately; the daemon then unwinds
its session manager, its phone server and its pollers. That is normally
fast, but a daemon whose database has been migrated out from under it fails
every read while it winds down and has been observed taking over five
seconds — which the previous five-second bound missed by a fraction,
reporting a stop that had in fact worked as did not stop and aborting the
restart that depended on it.
