My UP Athlon box went from two distinct failures in a loop of ten buildworld runs to zero failures in ten runs when I added these options. The failures generally manifested themselves as random corruption in the cached copy of the source tree which disappeared when the system was rebooted. Adding these options increased the buildworld time from 55 to 57 minutes per interation while in competition with setiathome. I hadn't attempted it before, but the system didn't have any problems with "make -j20 buildworld" when the kernel was compiled with these options.
