+// Experimental bug fix.
+
+// This code is an attempt  to prevent an  infinite loop.  It tries to
+// prevent  redundant  loader registration.  Explanation:  If a  given
+// loader is  registered two or more times, this leads to the creation
+// of a  circular linked list. There's a loop at another level that'll
+// traverse the circular list forever.
+
+// Note:  This fix is a kludge.  The problem should be  addressed at a
+// higher level.
