The man interpretation of vmstat running and blocked process:
Procs
r: The number of processes waiting for run time.
b: The number of processes in uninterruptible sleep.
The blocked here is not process waiting user input, it should include process
waiting IO and network. It should has same meaning with system load in loadavg
which include running(runnable) process and process in status of
uninterruptible sleep.

linux load average counts processes that are doing disk IO or network IO as
being 'ready'. they aren't actually running, but neither are they waiting on
user input ('blocked' per vmstat's version of reality).
