[running Windows 10]

Hi!

I have been rendering POV-ray animations for many years, all the way back to
Windows 98 days, when machines had only single cores. Now I have a Corei7
machine with 8 cores/16 threads. (Quite an improvement, ha.)

To be honest, I was not even aware that multiple instances of the app could be
run *successfully*...that is, with an overall speed improvement for a scene or
an animation...since it has always been my understanding that even a single
instance of POV-ray uses most of the resources of the entire machine for
rendering. At least, that's the way it used to be on my various single-core
machines through the years. (And AFAIU, initially *parsing* a scene uses only
one thread, regardless of how many threads are available.)

But the faster results of your multi-instance use are a real surprise! I will
have to give that a try, to see what the speed improvement might be for my own
animations.

There remains a question, though: When running multiple instances of the app on
multi core/multi thread machines, does each instance's scene parsing use it's
*own* single thread to do so? I.e., with 3 instances running (for example), are
there now 3 threads dedicated to parsing the (3) scenes? Or just one thread as
is typical-- split up between the 3 instances?
