Comment 5 for bug 1063690

As this change poses significant risk to the stability of precise, and I'm not convinced we have even found all the driver bugs it will trigger in precise, I don't think it should be on by default in any precise update.

After the requisite fixes to make unredirect work at all are backported, precise users probably should be asked to toggle the option manually if they want to try it. By CCSM or gsettings command.
