-   * In order to support web workers, a module must be aware that it can be invoked from multiple
-   * different JS VMs. Supporting web workers means recognizing things like:
-   *
-   * 1) ids (e.g. timer ids, request ids, etc.) may only unique on a per-VM basis
-   * 2) the module needs to make sure to enqueue callbacks and JS module calls to the correct VM
-   *
-   * In order to facilitate this, modules that support web workers will have all their @ReactMethod-
-   * annotated methods passed a {@link ExecutorToken} as the first parameter before any arguments
-   * from JS. This ExecutorToken internally maps to a specific JS VM and can be used by the
-   * framework to route calls appropriately. In order to make JS module calls correctly, start using
-   * the version of {@link ReactContext#getJSModule(ExecutorToken, Class)} that takes an
-   * ExecutorToken. It will ensure that any calls you dispatch to the returned object will go to
-   * the right VM. For Callbacks, you don't have to do anything special -- the framework
-   * automatically tags them with the correct ExecutorToken when the are created.
-   *
-   * Note: even though calls can come from multiple JS VMs on multiple threads, calls to this module
-   * will still only occur on a single thread.
-   *
-   * @return whether this module supports web workers.
