I liked v1 better with a tweak or two

There's done more goto endjob after here which would seemingly skip the
defined event.

There's also another "if (config)" in the SHUTDOWN, SHUTOFF, CRASHED
case that would be missed due to a goto cleanup

I can fiddle with v1 slightly and have it do the right thing.
