Isn't this only for dirty entries? I don't think that's the issue on my system as they are all clean -- the delay is not in writing back dirty pages but in defragmenting space left by removing clean ones.

Yes , this is for dirty pages , i think you can also fix other performance problems by setting tuned to dynamic mode.

I wish there was a solution for this because about 3 minutes ago I just ran into a situation where the command sudo apt-get update would not work because the /etc/apt/sources file was being read from an OLD copy stored in Cache... I needed to manually clear cache in order for the new file to be read and Apt to work again. So unnecessarily labor-heavy. I wish linux experience would not be so painful, because this been happening to more than 15+ years now. Very disappointing.

I can understand a file being held in Cache for long periods of time. But are you telling me Linux system does not have any kind of real-time verification for what of these files had changes in the meantime? A simple verification check would solve that. Back in my days, this was called a BUG.
