Comment 5 for bug 559915

This bug was fixed in the package dpkg - 1.15.5.6ubuntu4

---------------
dpkg (1.15.5.6ubuntu4) lucid; urgency=low

  * Backport from upstream:
    - Restore fsync during package unpack (LP: #559915). This is now done
      by deferring the fsync and rename for normal files in tar extraction
      so that it's done in one pass afterwards, to avoid massive I/O
      degradation due to the serialization from each write + fsync. When
      creating hard links to normal files on extraction use the .dpkg-new
      filename for source as the file is not yet in place due to the rename
      deferral.
    - Fix dpkg to not lose package metadata on filesystems where readdir()
      returns new files added after the opendir() call, btrfs in particular
      triggered the problematic behaviour. Closes: #575891
    - Report deferred trigger errors on status-fd. Closes: #574599,
      LP: #540252
