If I understand correctly you save the identity of such a buffer via

         (list (window-buffer tree)

hence you have an entry for that buffer in the saved window tree.  Let's
call the buffer B and the window W.  Suppose now you eventually want to
`winsav-put-window-tree' the tree you saved.  When you create the new
window, say N, corresponding to W you make it display B (provided B
still exists).  Next you check all windows in the new window tree.  When
you check N you know that it (1) displays buffer B, and (2) is a replica
of window W.  Now you scan B and for any overlay in B referencing W you
make the overlay reference N unless W is still alive.  All other
overlays in B are ignored.  Where is the problem?  Try to describe a
scenario that introduces an inconsistency in my proposal.
