I just had the problem looked at by the tech at the dealer. He agreed
on the behavior, but said it was "normal" for the 6 speed models. His
guess was that it was a work-around for a problem with the
transmissions, a way to hold the rpm up on upshifts. A ****-poor
engineering choice in my opinion (and his). Instead of fixing the
problem, they made the throttle stick!!??

Does anyone know of a solution?
