nit: add a comment saying "// Cleanup."

could you check the intermediary state here? (ie. do request())

ditto

Actually, could you do above:
  return Promise.all([setPermission('geolocation', 'denied', ...),
setPermission('notifications', 'denied', ...)]);

minus typos and inability to write JS on the spot

[Lalit Maganti, 2015/09/24 11:24:35]

Done.

[Lalit Maganti, 2015/09/24 12:43:39]

Realised that Promise.all does not work with the workers because there are all
sorts of cross promise issues with your custom test setPermission magic.
Switched back to chained set.
