+Time a repeated Python run
+--------------------------
+
+Usage: python3 lazytiming.py              # uses PySide6
+       python3 lazytiming.py <any arg>    # uses PyQt6
+
+It runs the same python for the testing.
+
+Actually comparing PySide6 and PyQt6 in action:
+
+    PYSIDE6_OPTION_LAZY=0 python3 sources/pyside6/tests/manually/lazytiming.py      # normal
+    PYSIDE6_OPTION_LAZY=1 python3 sources/pyside6/tests/manually/lazytiming.py      # faster
+                          python3 sources/pyside6/tests/manually/lazytiming.py xxx  # PyQt
