I just rendered this scene

 #declare Test=union{
  #local C=0;
  #while(C<40000)
    cylinder{0,1,2}
    #if(mod(C,100)=0)#debug concat(str(C,0,0),"\n")#end
    #local C=C+1;
  #end
  pigment{color rgb 1}
 }

and it returns "Peak memory used:         18142448 bytes"
but of course it not play with light buffer and other things

ABX

#declare _=function(a,b,x){((a^2)+(b^2))^.5-x}#default {pigment{color rgb 1}}
union{plane{y,-3}plane{-x,-3}finish{reflection 1 ambient 0}}isosurface{ //ABX
function{_(x-2,y,1)|_((x+y)*.7,z,.1)|_((x+y+2)*.7,z,.1)|_(x/2+y*.8+1.5,z,.1)}
