I tried this on several web pages that trigger crashes and it worked on
some, but on others, it didn't work. Even though the dock indicated the
application was not responding and it's name was in red in the Force Quit
window, it still returned a value on the get application command.

But, this worked:

try
    with timeout of 15 seconds
        tell application "Safari"
            zoomed of window 1
         end tell
    end timeout
on error
    KillSafari()
end try

on KillSafari()
    do shell script "killall Safari"

end KillSafari

It's possible that any number of commands could work rather than zoomed of
window 1, I'll try a few and see. Maybe a command that doesn't require an
open window would be more versatile.


I'll give the shutdown script a go later on, but this has been a big help,
thanks again!
