I might be even more aggresive on patch 2 when turning down the
bandwidth. :)
Another thing I thought about on the hang issue is that maybe we can
give a timeout for the waits and when the timeout triggers before a
directly assert in the test case we send sigabrt to QEMU (just like
what kill_qemu does) then we could have a chance to see the cores.
Not sure whether that could help, though.
