When I first switched to my current motherboard, I wanted to do some before and
after comparisons of the stack guard changes.  I don't happen to remember what
svn revision I was working with, but I was plagued by the rename bug.  I'm
pretty sure it was somewhere between the ino64 changes and the stack guard
changes.  It bit me once on a buildworld/buildkernel with /usr/obj on ZFS.  It
broken quite a few poudriere runs where I use tmpfs for most things.  I also
saw failures when I ran poudriere with tmpfs disabled.  For me it wasn't
confined to tmpfs, but it *seemed* to happen more often with tmpfs.  It was bad
enough that it hid a bunch of the other stability issues.

After serveral days, I upgraded to a different svn revision and the problem
went away.  I'm currently on r320570 and haven't seen the problem in weeks.
