...set a threshhold of 1/250th of a second. I never call usleep() if the configured delay setting is less than that. The full source of the entire method, and the Release and Debug build assembly codes are at the end of this mail. For clarity I show only the pertinent lines of code right here: useconds_t usecs = (useconds_t)( self.delay * (float)500000 ); if ( usecs >= 4000 ){ // ~ 1/250 sec usleep( usecs ); // usecs is ZERO!!!! } self.delay is an Objective-C 2.0 property that holds the current value of the speed slider. When set to maximum speed, usecs will always be ze...

...n this case, it applies the "hs" predicate to the subsequent call to _usleep.  I'd have to double check, but I'm fairly confident that the hs condition code is equivalent to >= for integers. All of my regression testing so far has had my speed slider set to its maximum, so the useconds_t has always been precisely zero. Maybe there's something special about zero that would not be the case for an integer ranging from 1 to 3999. I'll check that out, but not right now, I'm about to pass right out, but I don't want to because I am even more hungry than I am tired. The...
