   I've run some perf tests on this. First a very basic performance test. Below 
are metrics for network traffic between nodes. The first image is for current 
mango. The second image is CouchDB with this PR.

   The graphs are not at the same scale which is a bit frustrating. There is no 
regression and a slight improvement on network traffic. 
   Then I ran a full regression test:

   There are no regressions and in some cases a nice performance improvement.
