memory and cpu time statistics for 2008-09-19
There has been a 13% compile-time regression on this PR since September 19.
Looking at the statistics, it appears that there is a general increase in cpu
time in things that deal with df-chains.
This is the timings from 9/18; I'll include last night's times next.
