Package atomic provides atomic operations, independent of sync/atomic,
to the runtime.

On most platforms, the compiler is aware of the functions defined
in this package, and they're replaced with platform-specific intrinsics.
On other platforms, generic implementations are made available.

// as there is no connection between handling a signal and receiving one,
// but atomic instructions should minimize it.
