 // completion callback helper
 
 // A helper class for completion callbacks, designed to make it easy to run
 // tests involving asynchronous operations.  Just call WaitForResult to wait
 // for the asynchronous operation to complete.
 //
 // NOTE: Since this runs a message loop to wait for the completion callback,
 // there could be other side-effects resulting from WaitForResult.  For this
