pointer grabs should time out

[Torgeir Veimo]

I encountered a problem again today that has hit me several times over
the years; pointer grab by an X11 client that crashes. This has the
potential to take down the entire session. It happened to me when I used
acroread and selected a pull down menu, when it immediately crashed
after grabbing the pointer.

Shouldn't pointer grabs automatically time out after a given period of
time? This is a serious issue which can make a casual user believe the
entire server has crashed.
