Actionscript :: SQLite Insert Statements In A Transaction?

I'm trying to get my head around how to do a SQLite bulk insert using transactions in Flex / Actionscript 3 (using Adobe Air 2). This works, but it doesn't make sense to re-create a new SQLStatement in the loop:

private function onAddBulkContacts():void {
_responder = new Responder(resultEventHandler, errorEventHandler);
contacts_db.connection.begin(null, _responder);
var statement:SQLStatement;

[Code]...

But the latter code throw an error saying that it can't execute the second time through, since the statement itself is still executing (and I believe will be in that state until the commit). I guess I can understand that the statements get added to the execution queue, but it doesn't make sense that I have to add the SQL text within the loop, exactly the thing I'm trying to avoid. I'm sure there's a better way to do this, but I've spent way too long hacking and reading trying to figure out what the proper sequence is.
