-A Mutex is a mutual exclusion lock. Only one goroutine can enter the critical section at a time. Not until the call to the <tt>Unlock()</tt> function issued can another goroutine enter the critical section.
-Usage pattern (the curly braces are not necessary):
-<pre>
-var mutex sync.Mutex
-...
-mutex.Lock() {
-    // do something in a mutual exclusion mode
-}
-mutex.Unlock()
-</pre>
