Results from a run of my large FTP transfer test on this new release are...
interesting.

Overall time shows an improvement (6:28), though not enough of one to take the
lead over 2.4.13-ac7.

More interesting, perhaps, is the vmstat output, which shows this at first:

Previous tests showed fluctuating bo values from the start; this is the first
time I've seen them steady, so something in the patch definitely is showing
through here.

I've a couple more tests to run, such as combining -rmap11c with cpqarray and
eepro driver updates from -ac. I'll keep you posted.
