True. I don't know exactly what the best solution is. Something to do with 
singleton classes.

Not to mention the entire thread safety thing...

There's two solutions to that as far as I can see.

One is to put locks around the whole GVars3 database.

The other is to have all widgets sets operate using their own private 
string-tring map. Every so often, you will have to call a synchronize 
method which will synchronize the GVars database with the private map.

The second version is nice because it keeps gvars fast and you know that 
in your main loop, things aren't going to change from under you.

It works now. By the way, there's also --with-headless which creates a 
second version of the library which has all interactive bits disabled.

I was planning on doing the same thing for the commandline interface too 
at some point.
