A call to xname
adds the specified host to the access control list for the display.
>>STRATEGY
Get current acl.
If current list includes the host to be added:
Remove host with XRemoveHost
Get current acl.
Check that host to be added is not in the list.
Call xname to add host.
If call fails with a BadAccess:
Report that assertion can not be tested from this host.
Get new acl.
Verify that host is in new acl.

Report Pass.

Report that assertion cannot be tested.
