[lldb-dev] Ignoring Signals via the API

[Russell Harmon]

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?
