I find it pretty rare that i'll get hunting with it. The only time it really happens is if i'm too close to an object and not in the focus range, it will try and get it at any cost...
in day to day, it's a fast enough autofocus for caual use, and your subject isn't going to get anoyed at you for taking a long time to get focus... it just isn't lightning quick.
9 times out of 10 i use the center focus then recompose, so maybe this is why i rarely have trouble focusing as it's the strongest one. I am trying the other focus points a little bit more, but every time i've tryed, it's been copious amounts of lights, so no real issues yet.
