Hi Jesper,
Thanks for the review. I've made all of the changes per your comments in
my local repository. I'll post the updated patches after diagnosing what
I'm suspecting a memory over-allocation bug in one of the patches. If you
configure build with --enable-cassert, you'll see that throughput
decreases as number of partitions run into many thousands, but it doesn't
when asserts are turned off.
