The main issue with read_all is that it also acts as a stress
test. Reading some files in proc and sys is very resource intensive
(e.g. due to lock contention) and varies depending on what state the
system is in. On some systems this test will take a long time. Also
there are some files which have to be filtered from the test. This
varies by system as well.
