Hm, I'd prefer it with sob line since I very much want to again have good
reporting on missed interrupts (instead of silently papering over them).
If the simulator is broken we need to apply special duct-tape for it
(maybe in the form of a timer that regularly checks the seqno), since 1s
delay is simply too slow, even for simulators.
