When issuing 'reboot' to a VM with the no-reboot option, that VM will exit. When then issuing a shutdown command, the cleanup may race. Add calls to vm.wait() which will gracefully mark the VM as having exited. Subsequent vm.shutdown() calls in generic tearDown code will not race when called after completion of the call.
