Overview

Preload content of /sys/block to avoid deadlocks when loading from a different thread (issue with async IO and sysfs):

File.read('/sys/block/...') will hang if run in a multithread ruby process because it will use async IO
cat /sys/block/... will deadlock with the uptime command ran from agents's hearbeat callback
