runtime: document relaxed access to arena_used The unsynchronized accesses to mheap_.arena_used in the concurrent part of the garbage collector look like a problem waiting to happen. In fact, they are safe, but the reason is somewhat subtle and undocumented. This commit documents this reasoning. Related to issue #9984.

Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
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.
