Perhaps we should get together and take a look - 2 heads are often

We used to do this pre v0.5 but it was causing serious performance

We should definitely put this down as a new ticket on the trac [2]. I 
also don't think it would be that hard to do -- though whether it is a 
priority is another question :)
