Another question: When should the buffer-local reference be added?

Every time when point is moved to a new file?  Too frequent calls especially
in cases of e.g. pressing and holding the spacebar to move thru the file list.

Or when current-window-configuration is saved to a variable/register
or window-state-get is called?  I don't know what hook is possible
to use at that moment besides advices.
