GDK_DEBUG=no_grabs is the obvious solution, but it only works with
GTK+ built with --enable-debug.

I wouldn't be completely opposed to doing the Qt thing and automatically
disabling grabs when running under gdb. 

(Note: we can't take a patch for this from someone who looks at the Qt
source to see how it does it.)

But then again, that doesn't really solve the problem for language
bindings like Python, Java, etc, so maybe we just need to honor a
separate environment variable for turning off grabbing.
