I think Bruce wants per-backend data, and this approach would seem to only
get the data for the current backend.
Also, I really don't like the proposal to write files to /tmp. If we want a
perf tool, then we need to have something like 'top', which will
continuously update. With 40 backends, the idea of writing 40 file to /tmp
every second seems a little excessive to me.
