The Go programming language

What was happening on Issue 7010 was handler intentionally took 30 milliseconds and the proxy's client timeout was 35 milliseconds. Then it slammed the proxy with a bunch of requests. Sometimes the server would be too slow to respond in its 5 millisecond window and the client code would cancel the request, force-closing the persistConn. If this came at the right time, the server's reply was already in flight, and one of the goroutines would report: Unsolicited response received on idle HTTP channel starting with "H"; err=<nil> ... rightfully scaring the user. But the error was already handled and returned to the user, and this connection knows it's been shut down. So look at the closed flag after acquiring the same mutex guarding another field we were checking, and don't complain if it's a known shutdown. Also move closed down below the mutex which guards it. Fixes #7010 LGTM=dsymonds R=golang-codereviews, dsymonds CC=adg, golang-codereviews, rsc https://golang.org/cl/86740044 |

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 README). 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.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 doc/install.html for more details.
