Monitoring disk activity by process ID

[Ted Markowitz]

Is anyone familiar with a way of breaking down real-time disk activity 
stats (reads & writes over time) by the specific process ID's that are 
accessing the device in question? Every utility I can think of 
aggregates R/W activity at the device level and there's no obvious way 
to show who (that is, exactly which process or thread) is doing what to 
cause the reads & writes. I'm particularly interested in coming up with 
an easy way of monitoring exactly what process might be causing spikes 
in disk activity as they occur. Any thoughts or suggestions would be 
appreciated.

Thanks in advance.
