  lguest: fix occasional crash in example launcher. (2012-10-04 12:12:59 +0930)

----------------------------------------------------------------
New workflow: same git trees pulled by linux-next get sent straight to Linus.
Git is awkward at shuffling patches compared with quilt or mq, but that doesn't
happen often once things get into my -next branch.
