That was super helpful, I didn't know about -t. I've got one (hopefully last) issue with the test in that I believe I must be using the SBProcess.GetExitStatus() API incorrectly, as it always returns -1 for me. If that returned 0 when the debugee exited normally, the test would be finished. Thoughts?
