Ok, well, bonnie benchmarks with eight 1GB files, but I'm still seeing a 
50% performance reduction in reads. 1GB files fall into the "huge" 
category for me.

Alright, sounds like the general word is to just use the 1.4 branch, and 
don't roll it out until 1.4 goes stable. I'll try and get some 1.4 
packaging and benchmarking done tomorrow, and I'll see how it goes.
