I think Herbert was trying to add some balance to the equation.

Thanks.  This is the first indication I have seen that you even have broken-out 
patches.  Why those aren't in your source rpms is beyond me.  Everything
seems to have been posted in a 2-3 day window at the end of January and the
beginning of February.  Is this something you are now providing?

Shakes head.  You have a patch in broken-out that is 817K.  Do you really
maintain it this way as one giant patch?

As for the size of my code, sure parts of it are big I haven't really
measured.  Primarily this is because I'm not afraid of doing the heavy
lifting necessary for a clean long term maintainable solution.

Now while all of this is interesting.  It really is beside the point
because neither the current vserver nor the current openvz code are
ready for mainstream kernel inclusion.  Please let's not get side
tracked playing whose patch is bigger.
