A receive from an unbuffered channel is synchronized before the completion of
the corresponding send on that channel.

This program (as above, but with the send and receive statements swapped and
using an unbuffered channel):

<pre>
var c = make(chan int)
var a string

func f() {
	a = "hello, world"
	&lt;-c
}

func main() {
	go f()

      <code>/sched/pauses/total/other:seconds</code> provide additional details
      about stop-the-world pauses.
      The "stopping" metrics report the time taken from deciding to stop the
      world until all goroutines are stopped.
      The "total" metrics report the time taken from deciding to stop the world
      until it is started again.

are evaluated left-to-right and top-to-bottom; the first one that equals the
switch expression
triggers execution of the statements of the associated case;
the other cases are skipped.
If no case matches and there is a "default" case,
its statements are executed.
There can be at most one default case and it may appear anywhere in the
"switch" statement.
