Thanks for the tip. It is the way to determine if pidfile is stale.
But chances are that the PID is already assinged to another process.
So 'kill -0 $PID' is not definitely reliable.

Well, stunnel reload is not used very often so it may be excluded from
the init script. Simple start/stop are probably enough.
