IO wait is counted against load by linux. So high IO pressure, i.e. found in `/proc/pressure` will cause high load. When considering reclaim (dropped file pages which then need IO to read the page on demand again) it makes sense because high IO wait will delay reads (and writes) slowing everything down.
