 FTR, that report was the occasion to try out Org spreadsheet formulas,
 in order to compare =elisp-benchmarks= results.
+*** Region
+**** TODO [[bug:56662]] Improve region highlighting when multiple windows show the same buffer
+~highlight-nonselected-windows~ allows the following use-case:
+
+1. Set mark in buffer B1, window W1, and highlight a piece of
+   interesting text.
+2. Jump to window W2, displaying buffer B2.
+3. Work on B2.
+4. Glance at W1 to check again on the highlighted region.
+5. Go to 3.
+
+This breaks down when B1 = B2 (a buffer that is long enough that it is
+useful to show various parts of it in multiple windows), because
+marking something in W2 disrupts the highlighting *in W1*.
+
+Not only is the visual emphasis of the useful part of W1 lost, having
+the region face flashing on and off in W1 while trying to work in W2
+is somewhat distracting.
+
+The bug report has been closed, but Juri & Eli gave hints to make the
+mark (and therefore the highlighting) window-local.
