Comment 19 for bug 1431654

To add to comment #17, just now I replaced my empty 09_close_pipes.patch file with the actual patch, then rebuilt, installed and restarted the lightdm process. Upon logging in, it's back to using 100% of a cpu core again. So when the 09 patch is removed, no high cpu usage. When the patch is put back in, cpu usage is high again.
