When running the client header timeout test, there is a race between us timing out and waiting on the remaining requests to be serviced. If the client times out before the server blocks on the channel in the handler, we will be simultaneously adding to a waitgroup with the value 0 and waiting on it when we call TestServer.Close(). This is largely a theoretical race. We have to time out before we enter the handler and the only reason we would time out if we're blocked on the channel. Nevertheless, make the race detector happy by turning the close into a channel send. This turns the defer call into a synchronization point and we can be sure that we've entered the handler before we close the server.

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
