This makes me wonder: there's no substantial difference between clearing
the pool (and closing file) every 16 iterations, or doing that on every
iteration. So, what's magical about 16, do we actually know how many
files we keep open, does the code try to gracefully handle running out
of file handles, and if not, does the whole pack operation go south when
we do run out?
