go 1.1 improvements

[kbrock]

Thanks so much for this demo.

• The later version of Go automatically redirects, so I added a fix to not follow it. (otherwise benchmark fails for all urls)
• moved the bench and goto code into the src directory (I can undo this and resubmit)
• uses a local stat server rather than another directory (thanks for the go get command)

After the load starts getting higher, I do get a slew of errors, but I assume that is me not properly setting the sysctl values. Hope I didn't introduce a leak. (ports 808{0,1,2,3})

get: dial tcp 127.0.0.1:8081: can't assign requested address

Thanks!
