What kind of system are you on? It doesn't work so well for me.
I'm wondering too, I see a nearly constant 2ms delay added to the 10ms
sleep with select on both an Athlon64 X2 3800+ and an Athlon XP 2400+.Is there some YARV in there?

Have you all tried this outside of irb?
Just run the actual script itself + profiler to find out where the slowdown is occurring.
Try it with sleep and select versions. This might show some different points.. maybe not.
I tried your script on Windows under irb and using ruby and get similar results. I end up with times like 171.0, 171.0, 187.0, 203.0, 203.0,..., obviously select is not waiting, at least under Windows.
