True, although I was thinking more of something like the output of iostat, with 
data for each process, ie. a matrix of reads and writes to each filesystem or 
raw device, to show which process is doing what io on which device.

IOtop is useful for tracking total per-PID io, and in some cases that is just 
what you need, particularly on a typical desktop with a single drive.
