I can't, offhand, think of any real clean way to do this and keep the same
handle. Probably, you should be making "provisional" changes on a COPY
of the original resource, anyway. That way you'd have your OWN handle, you
could revert at will, and only if you wanted to KEEP the changes would you
copy the resource back to the RM's handle and call ChangedResource on it.
