I thought about doing something like that. I tried to write some code my
side with using an ets table but at the end of the day got no speed ups
coz ets:insert had to be called as I populated the cache. I suspect it
might be that the table had to keep growing. I haven't used ets much -- is
there a way of creating an empty table of certain size in one go?
