The default for many syslog setups is to buffer logging - especially with DHCP it makes a big difference to disk load and generally the advice is set syslog to buffered (async) mode for the logs with DHCP traffic in them.
I wonder if this could be the "long delays" that Mark is seeing with his Bash script ?

But this does seem like a broken client. It looks like it's not processing all options when it is forced to change IP address.
