+info: |
+  Atomics.waitAsync( typedArray, index, value, timeout )
+
+  1. Return DoWait(async, typedArray, index, value, timeout).
+
+  DoWait ( mode, typedArray, index, value, timeout )
+
+  1. Let buffer be ? ValidateSharedIntegerTypedArray(typedArray, true).
+
+  ValidateSharedIntegerTypedArray ( typedArray [ , waitable ] )
+
+  2. Perform ? RequireInternalSlot(typedArray, [[TypedArrayName]]).
+
+  RequireInternalSlot ( O, internalSlot )
+
+  1. If Type(O) is not Object, throw a TypeError exception.
+  2. If O does not have an internalSlot internal slot, throw a TypeError exception.
