Great, thanks for testing!  Pushed as

> Although it would be nice to have shepherd have a field in "herd status" which tells you when it respawned the service in < 1 s intervals (or maybe if it respawned it < 1 s after the initial start) - or maybe just how long ago it was (last) started and when the actual herd start command was :-)

In trying to implement that, I realized there’s a bug in respawn delay
handling.  More on that later.
