OK, I'll look at it when I get home from OLS.

I don't like the idea that the gc_node could go _backwards_ very much.
Although it should be fine really I'd like to know why moving it
forwards (in particular to NULL) was causing the code to break. 

If my assumptions about the behaviour were flawed, I'd like to know
precisely why. It might affect the other alternative too, just not as
obviously.
