Try this:

1. backup your defaults
2. Quit all GNUstep applications and kill all GNUstep servers   killall gdomap
        killall gdnc
        killall gpbs
3. delete NSGlobalDomain
        defaults delete NSGlobalDomain
4. run gdomap and gdnc again
5. immediately run this csh script:
        defaults write NSGlobalDomain dummy dummy
        foreach i ( `seq 0 1000` )
            echo -n `date +"%T"` "";
            echo `defaults read NSGlobalDomain dummy`
            sleep 1
        end

After some time the domain will dissapear:

08:13:57 NSGlobalDomain dummy 'dummy'
08:13:58 NSGlobalDomain dummy 'dummy'
08:13:59 NSGlobalDomain dummy 'dummy'
08:14:00 defaults read: couldn't read default
08:14:02 defaults read: couldn't read default


It seems, that if a program does not see some domain in database at program 
startup, it will not write it back. It may be a problem in -[NSUserDefaults 
synchronize] I think, but I am not sure.
