	This is a bit like asking "how long is a bit of string?".

	There are no limits on the number of zones[1] / number of
	records in named.  At some point the configuration will
	exceed the ability of the hardware / OS to support it.

	Serving 1 zone can push the machines limits, think of COM.

	[1] BIND 8 has a limit of 2**24-1 (16777215) zones.
