Description:
------------
I have a MySQL database with 250000 records which I try to 
convert to a Tokyo Cabinet Table database and I use this 
extension for that.

After approximately 200000 records get inserted, my code 
throws an exception "Unable to store columns: recv error". 
Further tries to insert throw the same exception. So it 
seems the socket cannot recv anymore.

I also tried with my own Tokyo Tyrant wrapper which is 
written in PHP and it works. So I think there might be 
something wrong in the extension regarding the way sockets 
are handled/released ?

It does the same thing whether connection is persistent or 
not.

Reproduce code:
---------------
foreach ($pdo->query("SELECT * FROM message") as $row) {
    try {

    $msg = array();
    $msg['subject'] = $row['msg_subject'];
    $msg['from'] = mb_convert_encoding($row['msg_from'], 'UTF-8');
    $msg['date'] = $row['msg_date'];
    $msg['messageid'] = $row['msg_id'];
    $msg['list'] = $lists[$row['msg_fkmlist']];
    $msg['inreplyto'] = $row['msg_inreplyto'];
    $msg['body'] = mb_convert_encoding($row['msg_body'], 'UTF-8');
    $tt->put($row['pkmessage'], $msg);
    } catch (Exception $e) {
        var_dump($e);exit;
    }
}


Actual result:
--------------
Unable to store columns: recv error
