I rebuilt everything from scratch and got results similar to Oren's, ie, roughly the same. This time I took off the test-coverage flags. (Sorry, I must have had them off for stock, but on with the Oren's patch). Before patch: real 2m57.416s user 1m12.830s sys 0m2.580s After patch: real 2m56.017s user 1m14.960s sys 0m2.380s I still have inlines turned off. Neal
