Is there a middle ground somewhere between allowing this willy nilly, and tainting the kernel? I too would love to get the TTM stuff fixed up, but every time I look at that code I am less and less confident that it will happen anytime soon. It's not even clear to me what all code needs to be touched. In other words, is there a way we can unblock David and friends, while still providing a forcing function of some kind to motivate/heckle the TTM (or whatever is making the allocations) to change?
