On all Unix-like systems I know, the load average is the average mumber
of processes running during a given time interval. I can't see what use
it may have to count load for _waiting_ processes.
I/O load is not process load, if a process waits for I/O completion it does
not use up its timeslice.

I tend to disagree.
