At the patch level, grsecurity and vserver have been very mixable, I've
had no other problems than the need to reduce chroot restrictions.

I've been trying to reproduce Justina's problem with gradm but I can't
reproduce it on context 0, It's only reproduceable inside a virtual
server but in such case it's a desireable behaveour.

It takes ~1 hour to integrate the .rej files and the resulting patch
looks clean enough.

Functionality overlaps in some places like process vissibility which is
filtered twice but I've seen no functionality conflicts other than
desireable restrictions inside chroot.
