    SubjectRe: 2nd Linux kernel patch to remove stack exec

    It doesn't. Actually, I always temporary turn my protection off while
    handling a signal, but it is enabled again for the rest of the code.

    Looking at the messages being posted on the subject, I think some people
    missed some of the stuff I explained in the message containing the 2nd
    patch. I intentionally made that message in form of a FAQ, thinking of
    the questions that are likely to appear. So I suggest to have a look at
    that message once again. :)
