What's the purpose of the for loop in the main of runtime.proc

Technical Discussion

I encountered following code at the end of the main func of https://golang.org/src/runtime/proc.go (Line 221 for the version at the time of this post):

exit(0)
for {
    var x *int32
    *x = 0
}

Anyone know what’s the purpose of the for loop?

Thanks.

It’s after exit, never executed. Perhaps, if you remove the exit line, the loop keeps the program running infinitely.
