Yeah.  Linus, as you can see from the story quoted above, I'm busy
rebuilding my primary workstation after frying four SSDs (doh!).  I've
reviewed the patch Leon is referencing here and I'm fine if he sends it
to you, or you can wait about a day or so and I can get it to you
(reinstall is done, now working on the restoring of backups, should be
mostly normal by sometime tomorrow).
