Intentionally create an unresponsive graphical process
Sometimes I want to test how a graphical application behaves in response to SIGTERM, SIGQUIT, xkill, and that pop-up that says "Do you want to terminate this application?"
What's a simple and reliable method to intentionally create an unresponsive graphical process, with the idea of running it under e.g. strace?

The exact answer will depend on the framework etc.
The common "thread" on all the GUI frameworks, is a central/main event handler that receives the events/requests to redraw, keyboard and mouse input etc.
That is then the handler where you can have a event that will not respond back, but sit in a tight while true; do nothing; done loop.

I'm not particular about framework, anything quick and dirty will do.

You could knock out a GUI app in a few lines and wrap it in something that caught your signals. Tkinter with python say is pretty trivial. See here
