Slave nameserver question

[Cherney John-CJC030]

Besides being a bad idea from a general design perspective, is it
possible to set up a nameserver as a slave for a domain, but have the
masters field point to itself? ("I am a slave for this information, and
the master is myself.") In thinking about it, it seems like it should be
OK. The slave will always be able to contact the master, so the data
should never go stale. The serial number is always up to date, so there
won't be any bandwidth used in zone transfers. Is there something
somewhere that would make this not work? (Something in the code for
executing refreshes or parsing the named.conf file?) 
 
Thanks in advance!
