  Test that Atomics.wait returns the right result when it was awoken before
  a timeout

  Atomics.wait( typedArray, index, value, timeout )

  2.Let i be ? ValidateAtomicAccess(typedArray, index).

      2.Let accessIndex be ? ToIndex(requestIndex).

      9.If IsSharedArrayBuffer(buffer) is false, throw a TypeError exception.
