Ah I see...

Well I think it should be _in any_ case secured, that only full lines are
And it should be configurable to have them immediately flushed (which is
AFAIU what flush_line does, right?)
Guess both is needed to use the logging e.g. with things like fail2ban.

In addition it's of course nice, if one can choose a number of seconds,
after which flushes take place (but then also only full lines should go out

Thanks anyway :)
