If we run a script or a plugin operation and the execution of it takes a long time, there is no real way to abort it other than killing the whole Ai process completely (since there is no dedicated one). This can loose us data, and saving each time before running a script or a plugin is paranoid and is hardly a solution.

We need to be able to hit Escape when a script or a plugin makes Ai freeze and expect for it to be stopped, perhaps with a confirmation.
