Hey Ulrich,

Thanks for articulating that requirement. I think it can be met by
extending the patch a little bit. We can keep the main thread parked
inside sys_exit /and/ get it not to react to signals internally, yet
have the external behavior that the process reacts in the normal
way to certain signals like SIGTSTP, SIGCONT, etc.
