      > db.user.insert({ x: 1, _id: 2 })
> db.user.find()
{ "_id" : 2, "x" : 1 }
> db.user.drop()
true
> db.runCommand({ insert: 'user', documents: [{ x: 1, _id: 2 }]})
{ "ok" : 1, "n" : 1 }
> db.user.find()
{ "x" : 1, "_id" : 2 }

      Not sure if moving _id field to the front is the desired behavior, but eval8.js fails if we switch to using write commands because of this.
