Sorry to turn up late here, but I strongly disagree with the notion
that this is a bug in the DSM or DSA code. It seems to me that it is
the caller's responsibility to provide a valid resource owner, not the
job of the called code to ignore the resource owner when it's
unusable. I suspect that there are many other parts of the system that
rely on the ResourceOwner machinery which likewise assume that the
ResourceOwner that they are passed is valid.
