* dynamic window manager is designed like any other X client as well. It is
* events about window (dis-)appearance. Only one X connection at a time is
* allowed to select for this event mask.
*
- * Calls to fetch an X event from the event queue are blocking. Due reading
- * status text from standard input, a select()-driven main loop has been
- * implemented which selects for reads on the X connection and STDIN_FILENO to
- * handle all data smoothly. The event handlers of dwm are organized in an
- * array which is accessed whenever a new event has been fetched. This allows
- * event dispatching in O(1) time.
+ * The event handlers of dwm are organized in an array which is accessed
+ * whenever a new event has been fetched. This allows event dispatching
+ * in O(1) time.
*
* Each child of the root window is called a client, except windows which have
* set the override_redirect flag. Clients are organized in a global
- * doubly-linked client list, the focus history is remembered through a global
+ * linked client list, the focus history is remembered through a global
* stack list. Each client contains a bit array to indicate the tags of a
* client.
