Under what circumstances is a deadlock a good thing?

Question

What is an example of when a deadlock is beneficial?

Answer 1

If the program you're deadlocking is a virus?

If you want to freeze up a process, I suppose that would be the only time you should do it... lol.

Answer 2

It's beneficial in that it clearly demonstrates you that your code is buggy and your synchronization methods need to be revised.
