Now with those fancy finish features recently shown off in 
povray.binary.images.

Also does stochastic global illumination now.

are there any other parameters (besides count and brightness) that work 
in this mode? changes.txt says most don't ... just curious

Just browsed the list of all the settings; The following should still 
have an effect:

     brightness FLOAT
     count FLOAT
     gray_threshold FLOAT
     recursion_limit INT
     adc_bailout FLOAT
     normal BOOL
     media BOOL
     subsurface BOOL
     brilliance BOOL

All others are just concerned with sample caching.

It seems that nothing appear when a scene like this is rendered. The 
image is black if version is 3.7; rather unofficial patch 3.7;

version 3.7;
//#version unofficial patch 3.7;

camera {
	location <15, 15, -15>
	look_at <0, 0, 0>
	angle 90
}

//background {color 0.5}


plane {
	y,-1
	pigment {color 0.25}
}

box {
	<-1.00, 0.00, -1.00>,< 1.00, 2.00, 1.00>
	texture {
		pigment{ color rgb<1.00, 1.00, 1.00>}
		finish { phong 1 reflection{ 0.00 metallic 0.00} }
	}
}

light_source { <20, 20, -20> color rgb 1 }

Oops, I have missed the # before the version directive, it is why all is 
black (even with pov3.7). I have an parse message which says there is no 
objects in scene.

what would be the best parameter to use if I'm seeing artifact in 
corners (shadow of an object hits floor and wall and it's darker where 
the wall and floor meet) ... I want to say count, but I also have an 
emission object, so I'm wondering if adc_bailout might also come into play

No, with no_cache the count parameter is less about quality and more 
about render speed.

But I'd have to see the artifacts to think of a reason why they'd be 
there and how they could be avoided.

I found under some conditions you get a visible pattern to the noise 
when doing a low quality "preview" render with no_cache. It's almost as 
if the random number generator is seeded off the pixel coordinate or 
something? Is this possible or am I seeing patterns where none exist?

A simple way to check that: Launch a 2 or 3 frames animation with no 
changes between the frames.
If there is a repeatable pattern, the images will show the same pattern. 
If the pattern is just random noise, it will change from frame to frame.
