Thank you. I've grabbed it. I'll need my morning coffee too! :-)

Thinking I'll do some real profiling again. It's gotten to be a year or 
more since I've done any - and I'd like to look at rtr that way too.

With rtr I can tell some of the delay with smaller render sizes is the 
mutex locking mechanism itself. This aligning with a note I'd guess 
Chris made way back when in the code. Beyond that I'm not sure what 
profiling might reveal - or not.
