:(  I'm gonna have to go with this is a thing now.
povwin 3.7.1-alpha.8358383+av65.msvc14.win
I think you built it.


I was starting up to run 100 frames. I looked at System Explorer 
7.0.0.5356 and noticed a handful of petabytes consumed by povwin (I 
don't remember how much, it was a lot).  I restarted povwin and started 
my render.  I notice it is leaking about 50MB per frame.
So I've done 48 frames and I'm sitting at
Mem Usage (KB) 1,972,724
VM Size (KB)   2,020,552

That works out to 42MB leaking per frame.  Seems low. What does the next 
frame give us?

Mem Usage (KB) 2,006,148
VM Size (KB)   2,055,804

It does give a little back between frames. It dropped to
Mem Usage (KB) 1,996,000

and then climbed to
Mem Usage (KB) 2,042,780
VM Size (KB)   2,094,184

I can't wait to see what it says when I get up in the morning...
...
99 frames rendered.

Mem Usage (KB) 4,217,172
VM Size (KB)   8,005,052

And then after it finished 100 frames and povwin went idle, it actually 
gave a little memory back and currently sits at.

Mem Usage (KB) 3,761,412
VM Size (KB)   8,055,384

This is the baseline memory usage for my next render job.  It will never 
go below this.  It will only go up.
