Re: inspect a thread’s stack

I think the conversation will shift a bit if you explain what you mean with: "// inspect the frames of that thread doing any needed business with them" What exactly do you have in mind? Do you want to change the stack in some way? Because, depending on what you want, Andrew's comment on: ThreadM
