+// the server until either it returns 0, indicating authentication/security
+// failure, or it returns 1, to indicate success.  A return value of 2
+// (actually anything other than 0 or 1) indicates that it should be called
+// back when there is more data to read.
+//
+// Note that the first time processMsg() is called, there is no guarantee that
+// there is any data to read from the CConnection's InStream, but subsequent
+// calls guarantee there is at least one byte which can be read without
