The os package sets a finalizer on *Process. I looked through all the uses of *Process in the package, looking for each case where a *Process was passed as an argument and the final reference to the argument was not a function or method call. I added a call to runtime.KeepAlive after each such final reference (there were only three). The code is safe today without the KeepAlive calls because the compiler keeps arguments alive for the duration of the function. However, that is not a language requirement, so adding the KeepAlive calls ensures that this code remains safe even if the compiler changes in the future. I also removed an existing unnecessry call to runtime.KeepAlive. The syscall.Syscall function is handled specially by the compiler to keep its arguments alive.

The Go Programming Language
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
For documentation about how to install and use Go, visit https://golang.org/ or load doc/install-source.html in your web browser.
Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.
Go is the work of hundreds of contributors. We appreciate your help!
To contribute, please read the contribution guidelines: https://golang.org/doc/contribute.html
Note that we do not accept pull requests and that we use the issue tracker for bug reports and proposals only. Please ask questions on https://forum.golangbridge.org or https://groups.google.com/forum/#!forum/golang-nuts.

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.
