>BPX ptrace...Does that mean performance is not an issue in that case? That seems like a logical conclusion.
When the system is running in a privileged state, just about the only safe way to give control to non-privileged work running as an exit or extention under that same task is via SYNCH. That is not going to perform well. Returning to the user in their state is a different case.
