one thing I noticed is that it looks like if the indirect symbol hasn't been resolved yet in the underlying process, it looks like we just give up. What if the user wants to call a function that the program hasn't yet called? Are there cases where this would blow up? Is there something more that LLDB should be able to do to force resolution?
