Actually, I realized that the particular R-pached I was using was from May
23. I used my June 4th version of R-patched (aka R-1.7.1 beta) and it
matches my June 4th version of R-devel, more or less:

 79.27 3.98 85.24 0.00 0.00
But, my 2003-05-23 version of r-patched produces a value that is roughly
half of that.
Not sure if that helps out at all, but the current r-patched and r-devel
is definitely slower in this then it was about a week and a half ago.
