Got it. That would be a socket issue. If I recall at the time I never found
a way to determine if a port was being used by another application or not.
I wish there was a way because then we could have Gnoga search for an open
port and then register with some registry app which ports an app are using
and load balance etc. thought the registry app. Would also allow for hot
swapping Gnoga apps and other niceties for larger systems.
