Your analysis exactly describes what happens in your current code, though I have to admit that my patch doesn't change it.
Without the patch my workstation (with ~180MB RAM) usually has between 50 and 80MB of inode/dentry cache and real usable stuff gets swapped out.
Either you can go make Linux 2.4 usable again for normal people, or you can go buy us all a gig of ram.
