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.
