Uh oh!

I have found that in the latest kernel BTRFS and also ZFS cache nearly every file that is touched and monitor Disk IO at the process level has become disingenuous. Your application may be reading and writing but under inspection the sysinfo will report no IO at all since its all read through memory.
From the perspective of someone who is trying to benchmark/debug their application, this is terrible. Because of this I have decided to include disk reads through cache in statistics. You can use BTOP if you need to see actual disk and socktop when you actual want to see usage.
If you think this is terrible let me know, if you think there could be usefulness with both, let me know and I could make a toggle.
Process details screen is checked into its feature branch, so feel free to build and give it a try.
