Nobody discuss about mystical or special in debug a debugger, but everything is about to invest lot of energy and time. Even launching GDB is a pain. And theres's a reason why many research live debugging using Smalltalk. When you debug a debugger you want as much as reflection as possible and Smalltalk has reified almost all of the internal machinery (see for example Moldable Debugger).
