IMHO as long as the difference from v18 looks reasonable, commit-by-commit regressions and improvements that even out in the end are okay. That's perhaps a bit of mental gymnastics (e.g., what if we had committed the inlining patch for v18?), but I believe that's how we've dealt with similar problems in the past. But maybe there are ways to avoid even these in-development regressions, too... -- nathan
