Agreed. Worse, it is not readonly. The /proc code task_lock's the task
struct, thus writing to it.
I'll post a patch shortly once I've tested it. Worse case only if the
task is exiting I sweep the tasklist looking for the parent to see if
the parent is still valid. I am not verifying if it is the actual
parent (it might be a new task allocated at the same spot). I could
just report 0 (or 1) for the parent for any process that is exiting, but
then you won't be able to see the ppid for zombies. Or is there another
state I can look for? What I really need is PF_EXITED :).
I am a little concerned also about mm, file, tty and sig fields. These
appear to be NULLed in do_exit(), but I haven't tracked down tty and sig
yet.
