All of the forked processes are going to share the same pty, so it's going to be literally impossible to distinguish the `O` packets, for instance. I'm wondering if it would make sense to split this interface into two, and have just one "preferred" recipient of `O` packets (and possibly others as well -- as we have no plans for supporting them right now), and have a separate list of recipients who would do things with the stop replies?

Specifically about the `O` packets, I've been thinking that it doesn't really make any difference which process receives them — after all, they will be printed all the same, won't they?



================

     virtual ~ContinueDelegate();
-    virtual void HandleAsyncStdout(llvm::StringRef out) = 0;
-    virtual void HandleAsyncMisc(llvm::StringRef data) = 0;
-    virtual void HandleStopReply() = 0;
+    virtual void HandleAsyncStdout(llvm::StringRef out, bool &handled) = 0;
+    virtual void HandleAsyncMisc(llvm::StringRef data, bool &handled) = 0;

I've figured out an explicit variable makes its purpose clearer, rather than arbitrary `return true/false`.
