Chrome extension: Execute background page only once when chrome starts

Question

I am playing with chrome extensions, my manifest loads a background page with:

...
"background": { "scripts": ["background_page.js"]

UPDATE: According to current documentation you simply have to delete the persistent key (no need to change it to "persistent": true).

This is an event page:

{
  "name": "My extension",
  ...
  "background": {
    "scripts": ["eventPage.js"],
    "persistent": false
  },
  ...
}

This is a background page:

{
  "name": "My extension",
  ...
  "background": {
    "scripts": ["background.js"]
  },
  ...
}
