The missing piece is being able to modify the mapping of the debuggee. Adding that is actually useful for a number of cases for a "normal" debugger as well. Consider conditional break points. It would speed up the processing a lot if a debugger could use JIT compilation and map the conditional handling into the target process. Joerg
