+/* A few comments about stacked cycling:
+ * When stacked cycling is turned on, the focused window is always at the top
+ * (front) of the list (_clients), EXCEPT for when we are in cycling mode.
+ * (_cycling is true) If we were to add the focused window to the top of the
+ * stack while we were cycling, we would end in a deadlock between 2 windows.
+ * When the modifiers are released, the window that has focus (but it's not
+ * at the top of the stack, since we are cycling) is placed at the top of the
+ * stack and raised.
+ * Hooray and Bummy. - Marius
