> Long compactions currently drop cache behind reads/writes so that they don't
> pollute the page cache but short compactions don't do that. The bulk of the
> data is actually read during minor compactions instead of major compactions,
> and thrashes the page cache since it's mostly not needed.
> We should drop page cache behind minor compactions too.
