timeout before kill

[Soren Hauberg]

Hi
When I close a window and the application doesn't respond for X seconds 
Metacity asks my if I want to kill the application. This is a great 
feature that I really like, but...
I'm working on a rather slow machine so sometimes Metacitys timeout is 
too low and I'm asked if I want to kill the application even though it 
haven't crashed.

So my question is: can I change this timeout?
