Change subject: utils: Wait for terminated process ...................................................................... utils: Wait for terminated process utils.terminating was not waiting for a terminated process, passing the process to zombiereaper. This behavior may be disastrous storage and mostly unwanted for other code. When we run a child process touching shared storage, we must wait for the child process. If we kill the child process without waiting, engine may start the same operation on another host, while the original child process is still running, possibly in interruptible state, trying to write to storage. To avoid this issue, we always invoke wait() after killing the process. Special code that do not want to wait for the child process should not use this context manager.
