This commit introduces the cpu_iowait item, this is the percentage of cpu time spent waiting on disks. High numbers typically indicate that your system is not responsive due to disk IO. This commit also avoid sleeping inside the cpu_perc and cpu_iowait functions: waiting in either one implies lost info for the other. Signed-off-by: Kurt Van Dijck <dev.kurt@vandijck-laurijssen.be>
