It looks like the timer of the timoutHandler is created when the handler is wrapped in

go/src/net/http/server.go

Line 2312 in fdd0179

t := time.NewTimer(dt)

. By the time the request is actually made, timer.C will have already triggered.

This may be a documentation issue rather than a bug. I'm not sure.
