Losing the client-Xserver connection is a fatal Xlib error. While
the client can install a handler for it, the only way they can
prevent termination by Xlib is to longjmp() out of it. The handler
isn't intended to let you deal with the severence, but is merely
a way of telling you, "oh, by the way, we are going to call exit()
as soon as this returns so you better save anything you need to".
Mark.
