Map/Reduce mappers shouldn't be called with modifiable values. #150

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Map/Reduce mappers are currently passed the stored value as a modifiable map.
This is an unnecessary waste of cpu and memory resources, given that values are 
transformed into modifiable maps upfront, and mappers don't modify any value 
anyways.
