Results will take a while to slowly come together, you won't get complete numbers in the next five minutes. In fact you won't get complete results even by the end of the night, because there's always additional counting - of postals and so on - later. So calm down, take a walk, and stop pressing 'refresh' on the official results page.
Election results counts aren't like polling two months from an election - they tend to converge pretty quickly on a result. I'm sure we'll have a clear picture of where things stand within an hour.
Not with that sort of neck-to-neck race between the blocks.
Swedes will keep their calm anyway...
