I'm having trouble understanding your logic. How does 'always "redirects"' follow from 'probably' and 'if a "very rarely used" callback is present...and the application crashes and you touch the mouse'

But I have a solution (maybe) to that last problem: Don't play with your mouse when a prog is crashing.
