To be clear about Emanuele's response, the async API should look like this.
async.each(contents, function(content, cb) {
content.save(function(err, resp) {
cb(err); //lets hope err is null, but if it's not null, the err
will get propagated through to the final "errors" param below.
});
}, function(errors) {
res.status.(200).. ///OK
});
