9.5 Server Grabbing
Xlib provides functions that you can use to grab and ungrab the server.
These functions can be used to control processing of output on other
connections by the window system server.
While the server is grabbed,
no processing of requests or close downs on any other connection will occur.
A client closing its connection automatically ungrabs the server.
Although grabbing the server is highly discouraged, it is sometimes necessary.
To grab the server, use
XGrabServer().
To ungrab the server, use
XUngrabServer().
