config: Avoid race with loader/watcher thread in apps that use mapget.

[MisterGC]

I am using mapget in the following situation (written in shortened pseudo-code):

main(args)
{
     service = configService();
     service.subscribe((){
          set(CONFIG_PATH_ENV, service.configPath())     
     });
     return someExternalFuncSettingConfigPath();
}

The someExternalFuncSettingConfigPath() also relies on the CONFIG_PATH_ENV set, this leads to a race.

This workaround suffices for now, but let’s discuss a solution that aligns better with the design principles of ‘mapget’.
