We should also start thinking about tests. I suppose the smallest piece of functionality that could be usefully tested (with a lldb-server test) is debugging a process that forks, stopping after the fork, and detaching from the child. Shall we try making that work first?

+  if (!detached)
+    return SendErrorResponse(Status("PID %" PRIu64 " not traced", pid));

True. I suppose we could just go with whatever falls out naturally from the code, and not add any special code on account of that.
