Change the default for rfile to buffered, because that seems to make a
big difference in performance on some platforms.

An anti-patch is needed to revert the effect in CGIHTTPServer.py which
I'll check in momentarily.

Here's a patch for the ForkingMixIn which will prevent the server from
forking itself into the ground. Note: I've tested a very similar patch
(subclassed ForkingMixIn) but not actually tested this one. As you might
surmise, this was done out of necessity...

Here's the correct patch!

I noticed while watching (with lsof) my forking SocketServer app running
that I would get multiple processes listening to the socket. For the most
part, this doesn't hurt things, but if you terminate the server, this can
prevent it from restarting because it cannot bind to the port due to any
running children which also have the socket open. The following one-liner
fixes this.
