I heard about this problem... maybe a bug, or bad implementation?

Why are you waiting?
Shouldn't be too  hard to make something like this:

#declare MY_PIG = pigment { wood blah blah blah}
#declare PIG_FUNC = function { pigment { MY_PIG color_map {[0 rgb 0][1 rgb
1]}}
#declare FUNC = function { f_rounded_box (blah blah blah)}
#declare ROUGH = 0.05;

isosurface {
function { FUNC(x,y,z) + PIG_FUNC(x,y,z).red*ROUGH}
blah blah blah
texture {
pigment {MY_PIG color_map {[ wooden colormap]}}
}


Iso-woods are certainly a big help, but you can't know whether they'll be
available before the end of the round or not, and I guess Christoph won't
make them available before the final release is out.
