Really no difference here, I didn't want to pin the CPU by going back and forth between the two functions that make the XMLHttp call and the function that test for a result. I figured a 1/10 second pause would lighten this load slightly and be almost unnoticable to the user. All you'd have to do on mine is remove the setTimeout and call the function directly at the same spot.
