No, given that it takes me 2 days to build it, I think it's probably
just as well if the autobuilders handle it.

I didn't use NBD for this build; as I said, I couldn't get NBD to work.

No, the low CPU utilization means that the box spent most of its time
doing things other than compiling code.  On most architectures an X
build consumes upwards of 95% CPU if I don't have the machine doing
something else.

The low figure above is, I fear, a symptom of the completely crappy disk
I/O.  I could be wrong, though, and I'd love it if someone with more of
a clue enlightened me.

I haven't looked into it yet.
