+/* From: Denis Vlasenko <vda.linux@googlemail.com>
+ *	With certain combination of .config options fclose() does not
+ *	remove FILE* pointer from _stdio_openlist.  As a result, subsequent
+ *	fopen() may allocate new FILE structure exactly in place of one
+ *	freed by previous fclose(), which then makes _stdio_openlist
+ *	circularlt looped. The following program will enter infinite loop
+ *	trying to walk _stdio_openlist in exit():
