Re: Error?
"/me points out that I've profiled code effectively with millisecond-level resolution, MANY times."
Apple's profiler built into Xcode just checks 1000 times per second or so where the program counter is, and that seems good enough to find bottlenecks in your code. You don't need any resolution at all as long as you can manage to sample at 1000 random points in time every second.
