The only additional cost is that of one additional test during setup. Its not in the inner loop. Its no more expensive in the general case than any of the other setup flag testing we do to choose, e.g. fast vs. slow core. Just to be sure, I grabbed a fresh copy from CVS. I get 24.00 mops for each of three trials each of unpatched and patched. On patched with the -P flag, I get 30.26 mops on each of three trials. At least on my system, I've not affected the general case one whit.
