Title:
  2x100% CPU and memory usage growth when performing partition
  modifications via udisks

Status in abstraction for enumerating and managing block devices:
  Unknown
Status in “udisks” package in Ubuntu:
  Incomplete

Bug description:
  When unsetting the bootable flag on a partition using palimpsest, the
  following things happen:

  - udisks-helper-modify-partition and udisks-daemon processes use 100% CPU each
  - udisks-daemon chews about 18MiB of memory each second

  This problem exists regardless of whether the partition is mounted or
  not.
