@deprecated_ii Every webbrowser stores sites to disk when you havent used them for long. If it always has to do that often, tune it so it uses less. The fact it caches stuff is still good
@deprecated_ii The OS manages the hardware and lets the processes exist. Configuring processes is what process configuration is for, though I agree smarter cache limiting would be nice :)
@deprecated_ii OS does things like this with file systems for example. Automatically only uses free space. That's why "free" and "available" are different in free(1), but that's filesystems. Caching a cat pic is completely userspace
