Yup, I'm aware. osu8 runs everything in ram (all source and object files 
are in RAM), and the HD was never intended to take the load (small, 
slow, not redundant, and not expected to live a long life if it needs to 
spin that much). The Clang debug build -vg builder takes half the ram on 
its own at 17G, then it's running three other builders beyond that.

I had hoped that doing a make clean would fix its disproportionate 
footprint (the next largest builder is 5G), but apparently not so. I'm 
going to see whether we can buy another 32G RAM for it.
