Thanks for your response. What i meant was every process could have an account of how many bytes were read/written to various filesystems/sockets using read()/write() system calls.
We could dump this stuff in /proc and it could tell us which processes are heavily IO bound.
I am wondering if this information will be useful to anyone.
