Start the interpreter in it's own thread - and kill that thread. But be 
aware that this is not recommended. You have been warned.

Another option is to install a trace hook. Then you can stop the app 
whenever you want. But it's a major performance penalty.

The third and safest option is to use a second process - but then you 
need a IPC mechansim like RMI to access you're application objects.

So - you have to chose which painful road you'd take :)
