Now I am wondering what oldNs is even used for here, it seems from the libxml
code it is really only needed to "cache" a pointer to the xmlNs that

No, the oldNs list is also appended to in `xmlDOMWrapStoreNs`. It seems that
this namespace list is only used for memory management. From a quick look,
your changes to the PHP code will cause a memory leak.
