[omniORB] Strange omniORB domain socket behavior

I am using omniORB 4.0.7 and have found that Unix Domain sockets are  
tied to the hostname and if you change the hostname the IOR no longer  
works because it cannot get a usable profile with the new hostname.   
Is there a way to get omniORB to assume "localhost" if a unix socket  
is used, instead of looking up hostname?

Simple Example (Note: programs were in Python):

oldname $ ./echo_server -f /tmp/echo.ior
oldname $ ./echo_client -f /tmp/echo.ior "testing"
oldname $ hostname newname
newname $ ./echo_client -f /tmp/echo.ior "test again"

The following is my omniORB config file:

endPointPublishAllIFs= 1
endPoint             = giop:unix:
serverTransportRule  = localhost unix
clientTransportRule  = * unix

I have limited the CORBA objects to only use unix sockets because  
both the computer's IP address and hostname could change.
