Ouch, I'm afraid this is yet another case where Ruby's reflection isn't 
as useful as it could be...

You can get the backtrace via Thread#raise (set 
thread.abort_on_exception to true first and catch the exception which 
will have the backtrace) but it has the rather unfortunate side effect 
of killing Ruby in the process.

I really think that Thread#caller would be a good idea...

And I hope I'll be able to finally add a sensible GUI soon enough. 
Thanks for the kind words.
