pub(crate) const QUITTING_INSTANCE_WAIT: Duration;Expand description
How long a relaunch keeps at it when the running instance’s host didn’t
take its open_new_window: long enough for an instance that is quitting
to let go of the single-instance socket/pipe (its launcher holds on until
srv has closed every agent, up to SRV_EXIT_WAIT, via
upgrade::quiesce_srv).
