Your name sounds familiar, any relation with Jay 'Saurik' Freeman?

Perusing the web suggests that there is a "granularity" -- a minimum sleep time -- at which the behavior of the "nanosleep" function changes: For times shorter than the threshold, it simply loops, but for longer times it may in fact actually sleep, and give other processes a chance to run, Does anyone know what this time is (or what other, possibly related times are), for MacOS? The answer is likely processor and clock-speed dependent, so is there a way to obtain this information at run-time on particular Mac platforms?

Hello, Jay. I think that mach_absolute_time function does have the best resolution available. I was also discussed in performance-optimization maillist and appeared that mach_absolute_time is the lowest-level recommended function.
