You might redefine 'write' to save all output into a variable.
Something like

  OUT=""

  function write(...)
	  foreachi(arg, function (i,v) OUT=OUT..v end 
  end

Not the fastest code in the world, but it works.
For a faster solution, you could store in OUT a table of strings.
Otherwise, I guess you'd have to change liolib.c.
