ops, this is a docbug. earlier syslog-ng was able to do this, but this maxed
out CPU usage. It is not possible to decide whether new data arrived to a
file using poll(), since the main loop uses poll to wait for events, it
would be difficult to add this feature. (though not impossible) so for now I
corrected the documentation, and leave this feature addition for 1.5.x.
