TCP_CORK is good for your server

Christopher Baus has a great article on TCP_CORK.

Hopefully this weekend I can do some tcpdump action on apache, and look at how much packet fragmentation there is, since Apache does not use TCPCORK, but instead it only uses [TCPNODELAY](http://www.unixguide.net/network/socketfaq/2.16.shtml), which can result in non-optimal conditions if you do many small write()s.
