I don't know for sure whether the temp .rca file really ever worked as 
intended in 3.6.

Note that in order for the temp .rca data to be re-used, you'll have to 
start the second render in abort-continue mode.

Furthermore, 3.6 only stored "top-level" radiosity samples, i.e. those 
produced at recursion depth 1. If you choose a higher recursion depth 
and POV-Ray decides that it needs more samples in the final render than 
are available in the cache, it will have to re-compute quite a lot of 
"deeper" samples.
