It is nice and I've added crude etnernal loops for debuggint purposes.
On the other hand I ran several machines as servers that don't have
a monitor attached (some have a serial console). Believe I don't care
if I see anything after a panic, I just want that machine up again
as fast as possible, and have a look at the crashdump.
It's a nice feature, but I want to be able to turn it off, without
adding a kernel-hack (aka #if 0 ...) build a kernel for the server
