Looks like a bug in the tester not timing out these tests. It maybe timing out
but the kill may not be stopping qemu or the testing is missing the timeout
event. The fact qemu is not finishing by it's self is a contributing factor. It
would require some debugging to find out which it is.

Tests not finishing should be a handled state no matter the reason.

Can you kill these tests by hand? If so what was the kill command?
