Being a smarty pants. I was going to direct you to the command line 
+gsfile (I only learned about it in the last year or two) But I ran into 
a problem.
I created two files one with:

#declare TEX = texture{pigment{gradient y} finish{ambient .1 diffuse  .7}}
#declare B = box{0,1}

#declare C = 1;
#while(C <= 100000)
object{B texture {TEX} translate 1.1*C*x}
#declare C = C + 1;
#end

And got
----------------------------------------------------------------------------
Shadow Ray Tests:            239987   Succeeded:                     0
----------------------------------------------------------------------------
Peak memory used:         289583104 bytes
----------------------------------------------------------------------------

But with:

#declare C = 1;
#while(C <= 100000)
box{0,1
     texture{pigment{gradient y} finish{ambient .1 diffuse .7}}
     translate 1.1*C*x
    }
#declare C = C + 1;
#end

There was no Peak memory message.



I hope that makes sense.
Using Win7 Pov 3.7
