-// 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
-// reason, this class is probably not ideal for a general application.
