Description

Status commands and security status commands pack is executed every minute and
takes ~15 seconds. While other tasks just hangs. This is very confusing for
the user.

The way optimize status commands is to execute them reflexively, since
creating the processes itself takes a lot of time (~50 processes are created
each pack).
This reduces time of status commands to ~1.5seconds
