	I am thinking about changing the way we store results. I think it  
might make a lot more sense to use a database table for results. The  
Results worker has been problematic.

	So for now I suggest storing any results you need in a db table and  
get the results in rails from said table. I hope to have some time  
soon to work on this but I am pretty busy at the moment.
