Profiling some code that's running on Apple AppKit, and I had no idea that [NSString stringWithFormat:...] and NSRect's `-convertRect:fromView:nil` were so expensive. Like *really* expensive. (and, for the latter with flipped views, sometimes wrong, there are places I'm trying to do my own calculations, but dang!)

Nothing makes me feel the warm fuzzies like 2 years of Apple Developer forums thread saying "I have this problem too, how do we fix it?" I also strongly suspect that this would be way easier if I just had a freakin' Makefile rather than trying to point and click through trying to accomplish what I am.
