 I guess it goes without saying I could test with heartbeat disabled,
 which I'll do, but haven't got to get, as I've been running it further
 with it enabled. I don't have anything very specific to say except that
 it's evident that this only happens when X is running. I can run this
 machine without X for days and beat on it with all CPUs active building
 things, no issue. It can sit idle for half a day, start X and it almost
 immediately panics. (This is a Skylake CPU, BTW, which I understand has
 known architectural issues.)

 PS since heartbeat is enabled by default, we should probably install the
 heartbeat(9) man page. I can take care of that, if it helps.
