The bitbake-worker child on the SIGTERM signal handling send the SIGTERM to all processes in it's process group. In cases when the bitbake-worker child got SIGTERM after registering own SIGTERM handler and before the os.setsid() call it can send SIGTERM to unwanted processes. In the worst case during SIGTERM processing the bitbake-worker child can be in the group of the process that started BitBake itself. As a result it can kill processes that not related to BitBake at all.
