Actually, it doesn't measure TCP at all: unix domain sockets don't go
through the IP stack. On any system, unix domain sockets and pipes will be
faster than TCP over the loopback interface because there is much less
protocol overhead. On some BSDs, pipes use the same code as unix domain
sockets - I'm not sure if Mac OS X has copied the faster pipe
implementation from more recent versions of FreeBSD.
