I'd be surprised. In order to get the pause instruction you'd have to use inline assembly or intrinsics, at which point the compiler would just blindly generate what you wrote. Maybe a JIT compiler would do the right thing.

Why do you think that? Because compilers tend not to use the pause instruction? Any why would a JIT behave differently here?

  Yes, a compiler wouldn't have a reason to insert a pause instruction, except to implement a pause intrinsic or some other canned sequence.
