Or we can just backport the fix from mainline to 4.1 which changes the
immediate use iterators and eliminates this kind of problem. Bug 26854 and a
couple of small follow up patches on 4/28 and 5/2. They've been in mainline
since the beginning of may and should be stable enough... Makes a speed
difference too.
