 subject: krb5_rc_io_open_internal on error will call close(-1)
 
 If there is an error in opening the replay cache - memory is freed, but 
 close() is invoked with -1 (failure from open()).  While technically,
 close() will return EBADF in such a case, and nothing bad will happen,
 valgrind picks up on this and provides an error...
