You should REALY update to version 3.7. I've totaly stoped using version 
3.6.1 about 2 years ago...

Radiosity tend to be somewhat faster, even on only one core. You can use 
all of your cores using only one instance as oposed to needing as many 
instance as you have cores with 3.6.1. To use 4 cores with 3.6, you need 
4 instance of POV-Ray, 4 instance of the source files and have 4 
instance of the parsed scene. This greatly reduce the amount of RAM 
needed and can save you from using the page file = MUCH faster!
POV-Ray is only loaded once, as is the scene file.
Also, aa is greatly improved and faster.

With 3.6 and using radiosity, you always get discontinuities when you 
reconstruct your partial renders to get the complete image. It's also 
the case when you resume a render with +c. It's no longer the case with 3.7.
