Josh Wills commented on CRUNCH-121:
-----------------------------------

John, thanks for this, it looks right to me. I'm going to integrate your patch w/an adaptation
of the unit test you provided to text the fix and post it here so [~kiyan] can take a look
at it tomorrow morning and check that there isn't an edge case here I don't see.
