I've looked, it's really not a big deal, I'm happy to do it, and I
want to, since the memory implications for the loader are *massive*
(fixing the loader requires more than just adding one line, it
requires a replacement for lwfree_poly which actually does the deep
free... so, 8 lines :) But still feels wrong to be building what
should be library infrastructure into the loader.
I'm going ahead with it, it will allow me to finish up the GUI. Which,
BTW, feels like a step backwards in code attractiveness, since I
didn't re-write the core code in the end, just retrofitted the output
handling.
