It ought to be reasonably easy to make them per-sb at least, I think.  We
don't allow cross-super rename, right?

Right now the sequence count handling very much depends on it being a
global entity on the reader side, at least.

And while the rename sequence count could (and probably should) be
per-sb, the same is very much not true of the mount one.

So the rename seqcount is likely easier to fix than the mount one, but
neither of them are entirely trivial, afaik.
