Starting with Ubuntu 10.10, PTRACE is limited to only direct descendants. It is controlled by /proc/sys/kernel/yama/ptrace_scope * if it is 0, then it is not needed * if it is 1, then this IS needed * else there is nothing we can do (no bt will be made) FIXME: do we need to make child wait until prctl returns in main process?
