Lang import script timing out

Here's the error:

An AJAX HTTP error occurred. HTTP Result Code: 200 Debugging information follows. Path: /batch?render=overlay&id=7&op=do StatusText: OK ResponseText: Fatal error: Maximum execution time of 240 seconds exceeded in web_root\includes\database\database.inc on line 2136.

Here's line 2136: $return = parent::execute($args);

I set the maximum execution time (maximum_execution_time) to 3000 seconds in php.ini. Actually, maximum execution time may have been set elsewhere (for example, in the script that's being executed.

What about using load_data_infile (http://dev.mysql.com/doc/refman/5.0/en/load-data.html)? What about real ETL tool or even just gettext...? Anyway, it seems pretty cool to the webservers to have php doing something for 240 seconds....

I get this error consistently, every time I try to add the Japanese language. The line number changes, though, I believe. I'll update and let you know.
