This is a comment about the documentation in the IDL, which has already been
committed. This can be addressed in separate CL, but I wanted to record this.

Currently, the comment says:
   * @param[in] callback A <code>PP_CompletionCallback</code> to be called when
   * the protection request has been made. This may be before the protection
   * have actually been applied. Call QueryStatus to get protection status.

The above text assumes a successful request, in which case the status will be
PP_SUCCESS. We should also cover the failure case. If the callback is called
with PP_FAILED, there is no need to call QueryStatus().
