It happens to be a process that may have an optional inferior (item #4) being tested by the lldb test code running in #3.  But we're trying to kill 3, and all of its children, and have 3 core dump.  (We don't care about a core dump for #4).

Ahh ok I thought it was a core of the inferior.  My bad.  Anyway that doesn't change anything about what I said earlier about not needing the soft terminate logic on Windows :)
