Bug description:
  # set up vars, install packages
  # Note, haveged is just to stop gpg gen-key from blocking.

  $ sudo apt-get install --assume-yes --quiet lxc autopkgtest haveged

  # set up container
  $ sudo lxc-create --template=ubuntu-cloud "--name=$cname" -- \
     --stream=daily --release=$release

  # get some .dsc to build
  $ apt-get source python-boto
  $ dsc=$(echo *.dsc)

  $ dpkg-query --show lxc autopkgtest
  autopkgtest     3.3
  lxc     1.1.0~alpha1-0ubuntu3

  # try to build the dsc.  Sometimes this will work fine.
  # sometimes it will fail.  Heres an example failed output.

  Sometimes it will succeed.  For this failure case, the next lines after
  sending command to testbed would have been somethin glike:

  adt-run: DBG: got reply from testbed: ok /tmp/adt-virt-lxc.shared.vq82rc_3/downtmp
  adt-run: DBG: sending command to testbed: print-execute-command
