Title:
  reinstall system extremely slow

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  Image: 20131016.1 saucy amd64 desktop

  I started an install with "reinstall system" selected on virtualbox a
  little over 20 min. ago. At least for the past 15 min or so, it seems
  to still be stuck on the "Saving installed packages" step.

  A quick look at /var/log/syslog shows that it *is* making progress,
  but it's extremely slow. This was a test install for the iso testing
  before, so I didn't have loads of extra packages installed or
  anything.  Looking at top, I saw it alternating between dpkg-deb and
  rcu_sched being the busiest processes, each taking 20-30% cpu or so.
