Thanks for sending your patches to the list, and for working on this! I
have been most excited to see this develop internally, and I'm glad that
the new paths have been exercised enough to send the patches.

So, I'm quite interested to see what you find in terms of wiring this
code up to work with khash. If that's something that you don't have time
for, please do let me know and I'd be happy to take it up myself.

Other than that, this has been thoroughly reviewed internally, and so I
don't have much more to add to this patch than what we have already
discussed.


Thanks,
Taylor
