Upon further examination, total_bytes_read_counter and read_timer appear to be 
unused, so I removed them.

Ah, yeah that's a good idea, I fixed up those places where DiskIoMgr touched 
disk_states_. In the process of looking at this I realised that the "protected 
friend" thing I was doing didn't actually do what I expected, so I went away 
from that and just documented int.

I separated that out into a follow-on patch to make it easier to review. I 
think I'll squash the two before merging to reduce code churn in the git 
history, if that works for you.
