Not sure if this is worth reporting.. p = os.popen('sleep 1234') os.wait3(os.WNOHANG) os.wait3(os.WNOHANG) os.wait3(os.WNOHANG) Notice struct rusage return value. When wait3() succeeds on Linux, but no child was waiting to be reaped, &ru is not updated by the kernel, therefore it is passed uninitialized back to the user, essentially leaking a little bit of stack memory
