Yes, you're probably right : ) (I haven't tested it yet).

If it works, we could have a new button at the Text Window to execute
scripts in "Safe Mode".  Actually two buttons, the other for "Normal
Mode", our current ALT+PKEY.

Great, let's hope it IS solvable.

With newer systems I suppose this really isn't that bad.  It's easy to
hang Blender (try increasing too much the level of subdivision, for
example -- or better, don't do it ; )).  It may take some seconds, but
at least under linux, I can change to another window and kill the
Blender process.
