about locking

[abate]

I think the FAQ about migration on the doc a bit over complicated. In the end I added this
if statement in my code. $UNLOCK_MIGRATE is set to false and I can simply change
its value without messing up with "meteor mongo"

  if process.env.UNLOCK_MIGRATE
    Migrations._collection.update({_id: "control"}, {$set: {locked: false}})

hope this helps
