Purely as a possible workaround...

If you're running on a platform with X-windows and your IDL sessions are
running in an environment in which the console is known, then you could probably
use X-window PIXMAPs instead of the Z buffer.  E.g.,

    window,1,/pixmap,xsize=nx, ysize=ny
    ... plotting ...
    c = tvrd()

shouldn't actually send anything to the display.  

However if the IDL session doesn't know about an X-windows device
this won't work.  So if by non-interactive session you mean a job
on a batch queue this probably doesn't help, but if you just mean
that you're running IDL from a script it might do the trick.
