syslogd gets kernel log messages only once every 30 seconds or
at the top of the minute, whichever comes first. It seems
logtimeout() is only called once after the kernel log is opened
and then never again after that. So I guess syslogd only gets
kernel log messages by virtue of syncer(4)'s flushes ...?
