I sort of hope someday to be in an interview where they ask that question. I'm pretty sure I could go an hour straight on it. Possibly two. Obviously, they won't let me. But still, it ought to be fun... I'll probably get stopped somewhere around the CPU trying to figure out which layer of cache the kernel's event handler is in, if not before....
Come interview at Facebook for a Production Engineering position[1]. I bet you your interviewers will push you at least that far or I'll give you a free lunch[2]. Even if it's just for the interview experience.
[1] I work there and love it. My contact details on my user page.
[2] I'll give you a free lunch either way. No purchase required. Void where prohibited.
