Jeremy Huddleston Sequoia f72ff1f7ac XQuartz: Silence an expected TSan warning 
This code is safe.  If the data race fails, the result is that we take the
lock and recheck.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:

All questions regarding this software should be directed at the
Xorg mailing list:
