On Apple Macintosh Mini, 1.6GHz Core Duo (2 CPU, sse, sse2; but i686 only)
with Intel 945GM graphics (i915 driver) [5-year old first "Mac-tel"], glxgears
stutters horribly.  FPS averages between 5 and 9, although some spurts of 15
or so can be seen.  The text output says to expect frame rate synchronized
with refresh, but this is nowhere near the case.

On Apple Macintosh Mini, 2.3GHz Core i5-2415M (2 CPU, x86_64, hyperthreading capable)
with PCI 8086:0126 "2nd Generation Core Processor Family Integrated Graphics
Controller (rev 09)" [the currently-shipping Apple model] (i915 driver),
glxgears is sync'ed perfectly to the refresh (about 59.88 FPS).
