What I did is restore these buffer /after/ window-state-put. Because the 
information I needed is stored in window parameters.

I mean a dummy buffer for window-state-get to save. This buffer is not visible 
to the user in theory: I create it and put it in every window and call 
window-state-get, then swap back buffers and remove this placeholder. Then 
before window-state-put create this buffer, and window-state-put will put it in 
every window. Once I restored every windows’ buffer from their window 
parameter, I can kill the placeholder. The sole purpose of the placeholder is 
for window-state-get/put to have /something/ to save/display.
