Making a singleton of NautilusApplication

[Jaap Haitsma <jaap haitsma org>]

Hi,

As explained in my previous mail: "[PATCH] Jump To button in bookmark 
dialog always open browers window" that patch also solves some critical 
messages which were caused by the fact that nautilus_application_new is 
called again.

Correct me if I'm wrong but I guess that per process there should be 
only one instance of a NautilusApplication.

If so then I think it would be a good idea to make a singleton [1] of 
NautilusApplication. This will guarantee that there is only one instance 
of NautilusApplication and also access to the application object will be 
very simple. You can just call nautilus_application_get_instance as soon 
as you need the application object.

As far as I can see also of the NautilusShell there is only one object 
needed.

Do the maintainers also think making a singleton of NautilusApplication 
is a good idea?

Jaap
