I also experienced this on ARM, in opencmd. The $status var is set inside an event handler, so this looks like a typical race condition between the pipe closing on child termination and the signal being received by the parent process. I'm not sure why waitpid is being called in the signal handler, unless there is a very good reason for doing something inside a signal handler then it should be avoided.
