I saw the reference to potential slowness readline() in the python  
client. I will try and fix that and submit my changes, and the  
results of any changes it has on my performance problem.

I couldn't recreate the problem on my last batch of tests, but I  
think I was using a smaller sample size. It definitely wasn't the  
same as my original run.
