[lldb-dev] Call python script on stop?

[Ted Woodward]

Is there a way to launch another lldb thread, so I have the command prompt and a python script running at the same time?

Yes, you definitely want to handle events yourself.  The target stop hooks are fine for printing some variables and threads, etc, but I wouldn't try to update your GUI, etc, from there.
