**Fixes**:

- [#259](https://github.com/alecthomas/voluptuous/issues/259):
Fixed a performance issue of exponential complexity where all of the dict keys were matched against all keys in the schema.
This resulted in O(n*m) complexity where n is the number of keys in the dict being validated and m is the number of keys in the schema.
The fix ensures that each key in the dict is matched against the relevant schema keys only. It now works in O(n).
