As much as I hate to say it, the whole setNode interface for DSNodeHandles
...
is HOPELESSLY broken. The problem is that the embedded getNode call can
change the offset of the node handle in unpredictable ways.
As it turns out, all of the clients of this method really want to set
both the node and the offset, thus it is more efficient (and less buggy)
to just do both of them in one method call. This fixes some obscure bugs
handling non-forwarded node handles.
