What is the best way to execute mongodb admin/console commands programmatically from node.js? Specifically, I would like to export a mongodb collection using mongodump after performing a series of inserts. Something like this:

```
// requires and initializing stuff left out for brevity
db.open(function(err, db) {
    if(!err) {
        db.collection('test', function(err, collection) {
            var docs = [{'hello':'doc1'}, {'hello':'doc2'}, {'hello':'doc3'}];

            collection.insert(docs, {safe:true}, function(err, result) {

                // Execute mongodump in this callback???

            });
        });
    }
});

```
