 * <p>For instance, if <i>steps</i> is 5, one example sequence that will be tested is:
 *
 * <ol>
 *   <li>remove();
 *   <li>hasNext()
 *   <li>hasNext();
 *   <li>remove();
 *   <li>next();
 * </ol>
 *
 * <p>This particular order of operations may be unrealistic, and testing all 3^5 of them may be
 * thought of as overkill; however, it's difficult to determine which proper subset of this massive

   * comparison to determine equality of values. This technically violates the specifications of the
   * methods {@link Map#containsValue containsValue}, {@link ConcurrentMap#remove(Object, Object)
   * remove(Object, Object)} and {@link ConcurrentMap#replace(Object, Object, Object) replace(K, V,
   * V)}, and may not be what you expect.
   *
   * @throws IllegalStateException if the value strength was already set
