-// CryptoOperation vs CryptoOperationImpl:
-//
-// A CryptoOperation corresponds with the request from JavaScript to start a
-// multi-part cryptographic operation. This is forwarded to the Platform layer,
-// which creates a WebCryptoOperation. When the WebCryptoOperation eventually
-// completes, it resolves a Promise.
-//
-// To avoid a reference cycle between WebCryptoOperation and CryptoOperation,
-// WebCryptoOperation's result handle holds a reference to
-// CryptoOperationImpl rather than CryptoOperation. This prevents extending the
-// lifetime of CryptoOperation beyond JavaScript garbage collection, which is
-// important since:
-//
-//   * When JavaScript garbage collects CryptoOperation and finish() has NOT
-//     been called on it, the Platform operation can no longer complete and
-//     should therefore be aborted.
-//   * The WebCryptoOperation may outlive CryptoOperation if finish() was
-//     called, as the result is delivered to a separate Promise (this is
-//     different than what the current version of the spec says).
