Each user runs their own property service and registry.  The iors for each user's
services are stored in files in this directory.  When a program asks for a
reference to one of these services, library code finds the appropriate ior file
and tries to connect to the service.  The library code will launch a new
instance if necessary and store the new ior.

	The user's property service ior is stored in a file named <user>.propertyservice.txt.
	The user's registry ior is stored in <user>_registry.txt.

When cipres is installed on a network where the nodes share a filesystem, including 
this directory, the filenames are instead:

	<hostname>.<user>.propertyservice.txt
	<hostname>.<user>.registry.txt

since there must be one of each service running on each host for each user.
