 *
 * For example, to have a WebWorker access files in the main browser thread,
 * do the following:
 *
 * MAIN BROWSER THREAD:
 *
 * ```javascript
 *   // Listen for remote file system requests.
 *   BrowserFS.FileSystem.WorkerFS.attachRemoteListener(webWorkerObject);
 * ```
 *
 * WEBWORKER THREAD:
 *
 * ```javascript
 *   // Set the remote file system as the root file system.
 *   BrowserFS.configure({ fs: "WorkerFS", options: { worker: self }}, function(e) {
 *     // Ready!
 *   });
 * ```
 *
 * Note that synchronous operations are not permitted on the WorkerFS, regardless
 * of the configuration option of the remote FS.
