If the junk root is ignored, and eventually overwritten as more ea's get
inserted then I don't think you need to do any more.

If the junk root stays in the block and occupies space that would otherwise
be used, then we probably need to handle this.. I imagine a clever user
could DOS the xattr space by making large ones when the system is low on
free space...
