[lldb-dev] Ignoring Signals via the API

[Malea, Daniel]

If you run dotest.py with the "-t" flag you'll see a bit more of what's going on during the test execution...

Off hand I can't see anything clearly wrong with the test..But I haven't run it.

I'm having some trouble running lldb's test suite. I'm getting the error "AssertionError: False is not True : Current executable set successfully".

I've attached a partially complete test, but since I can't get the test suite working right now, it's not been run.
