I think you can't use reload in this scenario. Your framework would have  
to know which modules to reload, which names to rebind, which imports to  
re-execute, which objects to re-create... Reloading without intimate  
knowledge of how the reloaded module is used is hard, if not impossible.
Perhaps the best option is to run the tests in another process. Use any of  
the available IPC mechanisms to gather the test results. This has the  
added advantage of isolating the tested code from your GUI testing  
framework; all requested resources are released to the OS; the tests run  
in a predictable environment; etc.
