Do you have any profiles to back this up? My concern is that the things
we do that generate logs are quite file system intensive and it is not clear
to me that the CPU usage is important. I'm happy to be proven wrong, though.

We also have a format for tuples used in the entries files. We could make the
routines that read and write entries files more generally useful.
I don't see any real disadvantages/advantages regarding either formats.
It is just that it might be better to use similar formats throughout the
WC admin area.
