That's a whole different type of test.

Exactly... see the comment I made about random stress, mixed load

Kernel crash=bug, even as root.  Rebooting is a normal expected system
behaviour when you tell it to do so.  Causing an oops or panic should
not happen even as root no matter what you are running, if it does then
it's a bug even running as root.

In most cases, this is true.  However the option exists to run the tests
in parallel for advanced users who know what they are doing.
