I am feeling better after reading that I was not a lunatic all the time. :)

Did you pass out some course about moderating OSS forums? :)

Well, it looks funny.
I do not want to get stuck in a loop. The stats of the daemon and
plugins are the last point, I do not want to gather stats of stats... :)

I have thought about a plugin without read() that could be configured
and called as the last plugin. It would get stats from the global

It is not in the form of usable patch.
I injected the plugin_read_all() with the check for p-type == "sensors"
| "sensor_voltage", DS definition, formatting the time spent and call to
