+Some of the use of the RECORD extension can leave a
+tiny window for XGrabServer deadlock. This is only if
+the whole-server grabbing application expects mouse
+or keyboard input before releasing the grab. It is
+usually a window manager that does this. x11vnc takes
+care to avoid the the problem, but if caught x11vnc
+will freeze. Without \fB-grab_buster,\fR the only solution
+is to go the physical display and give it some input
+to satisfy the grabbing app. Or manually kill and
+restart the window manager. With \fB-grab_buster,\fR x11vnc
+will fork a helper thread and if x11vnc appears to be
+stuck in a grab after a period of time (20-30 sec)
+then it will inject some user input: button clicks,
+Escape, mouse motion, etc to try to break the grab.
