Hi Robert,

While I am a developer, I don't have much experience developing in Linux
or using Bazaar (bzr).  With that being said, I wasn't exactly sure how
to disable a patch per say, so what I did was backed up
09_close_pipes.patch by moving it to my desktop, then issuing "touch
09_close_pipes.patch" to create a blank file with the same name.  I then
built the package and installed it.  After restarting lightdm, I have no
CPU issues any longer.  So it would seem that the bug is indeed in
09_close_pipes.patch.

I hope this helps.  I'll see if I can wrap my head around gdb to see if
I can provide any more information.

  Since updating lightdm today, one core of my CPU is always maxed out

  stopped.  I tried this with 2 different kernels: 3.2.0-77-generic and
  3.2.0-79-generic and and version 1.2.3-0ubuntu2.6 of lightdm still
  caused 100% cpu usage.
