I understand. But again, this depends on how you restore. For example, if you do not "transfer" libc/ld code, then probably vdso is not a problem. Just you need to ensure the task was not stopped "inside" vdso. Yes, yes, I understand that this is too limited, you probably want to transfer "everything".
