Well let's speak of triplicate names:

The name zeus is used for three sites in New Jersey, Oregon, and Great
Britain.

I am getting a bit tired of adding -dxyz!non_singleton_offender to
pathalias's makefile.  Someday soon the command string will be too long
to pass into the shell from make.  One solution would be to modify
pathalias to accept a dot in site identifiers but just output only the
sitename before the dot (easy), AND modify all the non-singleton names
in mod.map.uucp to the full domains (harder-best done once via
cbosgd!map and its volunteers).  I still wonder why the maps aren't
adequately check for non-singletons before they are sent out, a simple
script would show a small set of likely candidates.

For example:
		produces:

zeus.OR.UUCP		x(DEMAND)
		x!zeus
zeus.NJ.ATT.UUCP	y(DEMAND)
		y!zeus
zeus.HWCS.GB.UUCP	z(DEMAND)
		z!zeus

We could still have just:

ihnp4	x(DEMAND), zeus.NJ.ATT.UUCP(DEMAND),  ....
		ihnp4!x
		ihnp4!zeus

for now, and switch all of the database over to domains with time.
