I was seeing random-looking memory corruption on my Athlon box during
repeated buildworld runs without these options.  I've also got 1GB of
RAM, so the source tree would remain cached in RAM after the first run.
The memory corruption would show up as damage to random files in the
source tree and would disappear after a reboot.  A small section of the
damaged file would be turned into binary garbage.  The damage wouldn't
show up until I'd run buildworld 5 to 8 times. The system never paniced,
though that could easily be configuration and workload dependent.
