This is probably not the best way to do it but you could use strace to
trap writes to file descriptors (see man page on how to filter strace
output) and record how much is written to each descriptor. See
/proc/pid/fd then to see which files those descriptors correspond to.
As I said, there is probably a far neater way of doing thing.
