I'm no innodb dev, but from managing mysql databases, I can say that
mysql simply eats all the RAM the admin is willing to allocate for the
DB, and is content with the page cache almost not working.
IOW: mysql manages its own cache and doesn't need or want the page
cache. That *does* result in terrible performance when I/O is needed.
Some workloads are nigh-impossible to optimize with this scheme.
