 look at the reproducibility issues). boklm: Could you please have a look
 and test it on your machine(s)? One thing I am particularly interested in
 is your report about whether killing the old qemu process (from the
 previous build step) still works as it used to. It turns out on my machine
 I have to wait about an hour [sic!] until the process gets killed. If that
 is not just my machine I'd be happy to hear about possible workarounds or

 That's weird because after the first try you should have a `base-
 jessie-i386.qcow2` and during the second one (after killing qemu) you
 would create the 64bit one. Running `./make-vms.sh` again now should
 indicate that all images are created. Maybe you are seeing something
 different like the build is going trying to kill the qemu process dealing
 with jessie 64bit?

 Either way it seems you hit the same problem as I: the images are not
 shutting down properly. Any idea how to cope with that? Maybe we kill them
 right away in `stop-target` until we have a proper fix at least?
