Reason: Page not present or supervisor privilege. Nice! In that case I think the way to go is to audit the (probably few) places where kmpc_impl_malloc are called and add a check for whether the return value is 0. With that in place we can reland this and get more graceful failure (at a guess we should fall back to the host when gpu memory is exhausted? or maybe just print a 'out of gpu heap memory' style message and abort, don't know).
