LIMIT seems broken

vers. 0.5-rc3
```
SELECT * FROM server_disks_1 limit 1
```
This query returns 12 results instead of one in the admin interface, "LIMIT 2" gives me 24. Same happens on other series too.

Those are the returned timestamps:

1393577978000
1393459205000
1392854405000
1392249604000
1391644808000
1391040004000
1390435202000
1390406899000
1381968002000
1381363201000
1380758405000
1380153601000


Do I get one result per shard?
