Upserting keeps adding duplicates of the same record to the database

See the code below, upserting the same record three times in a row:

var Nedb = require('nedb');
var db = new Nedb({ filename: 'test.db' });
db.loadDatabase(function (err) { 
    db.update({ '_id': 'foo_id' }, { somedata: 'hello' }, { 'upsert': true }, function (err, numReplaced) {
        console.log(numReplaced, err);
        db.update({ '_id': 'foo_id' }, { somedata: 'hello' }, { 'upsert': true }, function (err, numReplaced) {
            console.log(numReplaced, err);
            db.update({ '_id': 'foo_id' }, { somedata: 'hello' }, { 'upsert': true }, function (err, numReplaced) {
                console.log(numReplaced, err);

            });
        });
    });
});

At the end of execution, test.db is:

{"somedata":"hello","_id":"foo_id"}
{"somedata":"hello","_id":"foo_id"}
{"somedata":"hello","_id":"foo_id"}

I’m on Mac OS Yosemite (10.10.1) running nodejs 0.10.33 and nedb 0.11.1. This issue goes well with the other one I found some time ago https://github.com/louischatriot/nedb/issues/217 . Thanks!

@louischatriot I come accross to this problem also, it would be better to make a notice in a subsection of update/delete section. no one reads the whole readme fro a simple update documentation. Thanks!

This is the expected bahavior, please read the readme before asking about sutff in it …
