No one will be able to call this function second time ;) Here is why (from t3lib_db):

function connectDB()	{
	if ($this->sql_pconnect(TYPO3_db_host, TYPO3_db_username, TYPO3_db_password))	{
		if (!TYPO3_db)	{
			die('No database selected');
			exit;
		} elseif (!$this->sql_select_db(TYPO3_db))	{
			die('Cannot connect to the current database, "'.TYPO3_db.'"');
			exit;
		}
	} else {
		die('The current username, password or host was not accepted when the connection to the database was attempted to be established!');
		exit;
	}
}

So it is either connected or dead.
