I'm not so sure. How is the cached route located and where is its
RTF_UP cleared? The route being deleted has its RTF_UP cleared, but
that's not the one ipforward_rt points to; unless the route is to a /32
or the packet is to the all-0 host portion, it can't be - the cached
route always has the exact /32 as its destination.
