Is log_in_vain really good or really bad?

I've actually seen something similar happen.  What happens, is when syslog 
gets backed up with lots and lots and lots of messages, it leaks a couple 
via wall.  I'm not sure why, but I've seen it happen.  Usually you only 
receive a fragment of a log entry.  Perhaps it's a bug in syslogd, but it's 
only occurred maybe 2-3 times with me, so I just wrote it off.
