It writes garbage into syslog and so syslog locks up.

Evidently what gets logged includes color codes(??) as part of the text. Attached is a tail of syslog. At this point it locks up and nothing further can be seen. Doing a tail -f /var/log/syslog, nothing else every shows up.

Here's what I get:

Doing od -a on syslog reveals that text is there, but both cat and tail lock up.
