Bug description:
  Installation of package memtest86+ fails, it does hang and never ends
  if lvm snapshot is present.

  Prepare:
  * create active lvm snapshot

  Test case:
  $ sudo apt-get install --reinstall memtest86+

  <hang>

  Recover from the hang with:
  $ sudo pkill -f 'frontend /var/lib/dpkg/info/memtest86\+.postinst'
  $ sudo killall grub-mount
  $ sudo umount /var/lib/os-prober/mount

  (don't kill grub-mount nor umount if you want the next run to
  "succeed", well not run)

  Actual problem:
  update-grub / os-prober leave stray grub-mount behing.
  workarounds applied in os-prober 1.57 doesn't actually help here.
  upgrading to quantal's grub2 package resolves the hangs.
  A minimal backport from grub has not been identified yet.
