Software nudges frozen computers out of infinite loops

Software nudges frozen computers out of infinite loops: "There are few things as maddening as being in the middle of a task on a computer, and having the software freeze up on you. This can be particularly enraging if you haven't backed up your work recently, and you know that the only way of 'thawing out' the program will be to execute a force quit - your work will be lost, all because the (insert word of your choice here) computer didn't know what to do next."
