+// 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.
