Per-file, per-process disk access statistics

Hi, folks. I want to diagnose which programs trigger disk writes,
so I'm wondering if there's a way to determine which processes write
to which files on what disks with what speed?

I know there are gstat(8) and iostat(8) which show how busy each
disk is, but they do not show which files are being written and
which processes are doing it.
