Easy. Nothing, since each task has it's own stack. However, the interviewer said I was wrong, I stood my ground, politely and explained: "each thread or task has its own stack and no shared memory." Was he testing my resolve? Anyway, he was wrong. He was looking for me to use the "reentrant" keyword, hardly even used anymore.
