Currently, various functions are marked with the comment // May run without a P, so write barriers are not allowed. However, "running without a P" is ambiguous. We intended these to mean that m.p may be nil (which is the condition checked by the write barrier). The comment could also be taken to mean that a stop-the-world may happen, which is not the case for these functions because they run in situations where there is in fact a function on the stack holding a P locally, it just isn't in m.p. Change these comments to state precisely what we mean, that m.p may be nil.

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.
