Thank you for the patch. I tried it and found the the process cloned by my test program became the zombie child of my shell and is not reaped because the shell is not expecting the process.
# ps lw F UID PID PPID PRI NI VSZ RSS WCHAN STAT TTY TIME COMMAND 000 0 1180 1176 14 0 3392 1640 wait4 S pts/1 0:00 bash 144 0 1249 1180 9 0 0 0 do_exi Z pts/1 0:00 [a.out <defunct>] 100 0 1279 1180 15 0 3272 1440 - R pts/1 0:00 ps lw
This is okay because when the shell is terminated, the child is also reaped, but it seems a little strange. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
