Could you be more specific? The tailcall sniffer is unusual that it needs to
unwind frame (PC) X+1 from frame X and then insert arbitrary number of frames
in between. So it needs to do "preliminary unwind" first.

I have tried various ways while coding it and I found the current
implementation to fit most the GDB codebase.
