[K12OSN] Fedora 10/11 performance fix



https://bugs.freedesktop.org/show_bug.cgi?id=17868
Apparently libxcb accidentally turned on "Nagle's algorithm" with TCP transmissions, which is especially bad for real-time stuff like X over the network. This causes a performance penalty for all X applications over the network, although some apps are more effected than others.

http://kojipkgs.fedoraproject.org/packages/libxcb/1.1.91/7.fc10/
Fedora 10 binaries

http://kojipkgs.fedoraproject.org/packages/libxcb/1.2/4.fc11/
Fedora 11 binaries

Please upgrade libxcb on your K12Linux Fedora 10 or Fedora 11 server and client chroots. We need confirmation that:

1) This doesn't cause any regressions.
2) This actually does help performance (on what applications?)
