i was experimenting a bit with cinap's version of dropping duppage, and for
the lame build the kernel tests there's quite a bit more i/o
duppage no duppage
read 45976291 53366962
rpc 73674 75718
you can see below that both end up reading 6909416 bytes
from 6c for 136 executions. 6c is only 264450 text+data,
so that's 26 unnecessary reads (6c had already been cached).
the original fairs better reading only 1816296, but that's
still way too much.
this needs a better algorithm.
