What is the watchdog good for?

I think “reset on hang” is an interesting feature for servers and server admins might like to manually enable it. However, for most users I think it would be desirable to have this disabled by default. Because should the VM hang, the current output might be helpful to figure out what actually caused the hang/crash. Auto reset would make debugging much harder.
