IIRC, The gdb team was previously talking implementing this by forking after every instruction. Does anyone know if the current functionality is being built on that model? I guess the advantage of doing it that way is that the majority of the memory pages can be shared if the OS uses a copy-on-write virtual memory system. This: Breakpoints and watchpoints will work in reverse -- allowing you for instance to proceed directly to the previous point at which a variable was modified. is going to absolutely killer functionality for reverse engineers.
