That's like saying that "if quarks were the size of soccer-balls, we'd all be pink". It makes no sense. When you claim that it's arbitrary, you're totally ignoring reality, and CPU design. The fact is, TLB's are very fundamental to task switching. filesystems are not. It's that simple. IOW, it's not at all arbitrary, it's a direct result of how the world works. The "world" for the kernel is the reality of CPU's, and in that reality, TLB switching is a huge factor. There is nothing arbitrary about it at all.
