LiveUser singleton and singleton Log

<code>
$LU =& LiveUser::singleton($conf);
$LU_logger =& Log::singleton('file', LOGFILE, 'ident', $log_conf);
$LU->addErrorLog($LU_logger);
</code>

Is this right?
If the LiveUser object was previously inited, and a log added, will this
add yet another log, so that you have twice the same log? If so, how do
I prevent that from happening?
