But inotify has the benefit of not needing regular polls, and immediate
notification when files change. I wouldn't want it for performance,
because it wouldn't give a noticable boost in this case. I like inotify
better in this case because of responsiveness, and effectiveness.

For example, if my low-power system is happily idling, I'd rather not
have syslog-ng regularly stat files and wake up the disk. However, if
the kernel signals us that hey, this stuff here changed, that's much
more efficient.

Sadly, I don't have such a system where it would make any difference,
but still! :P

syslog-ng-ctl reopen-files could be useful nevertheless, for different
purposes.
