Sounds like there's a hole in the stock tune. Somewhere, probably closed loop, possibly in an independent clutch-in map. I know the GM PCMs would crack the throttle a bit independently if you started to release the clutch and didn't add any gas at all.
I don't know about the second part, but I agree on your first part, it's not break-in.

My RSX has done this a handful of times after 100k miles. I assumed I needed a new fuel filter due to the mileage, but it went away by itself. It shouldn't be happening. It is possible the problem is bad gas though, maybe the guy a few posts up who has had his car in for 2 days can suggest trying fresh/good gas.

tagging for update.
