Summary: 
2.5.40 shows no significant difference from 2.5.39 (except in process_load; 
now equivalent to 2.5.39-mm1 - the significance of which is not clear of it's 
importance)

2.5.40-mm1 shows a substantial improvement under IO load (consistent with the 
change in fifo_batch as discussed under the thread "[BENCHMARK] 2.5.39-mm1")
2.5.40-mm1 also shows a slight drop in performance under mem_load. Note of 
interest that both 2.5.38-mm3 and 2.5.40-mm1 which have fifo_batch set to 16 
instead of 32 have both better IO load performance, and worse mem_load 
performance - related?
