Provide a real mechanism for fast invalidation by marking roots as invalid so that their reference count will quickly fall to zero and they will be torn down. One negative side affect of this approach is that a vCPU thread will likely drop the last reference to a root and be saddled with the work of tearing down an entire paging structure. This issue will be resolved in a later commit.
