-When the source “fires,” GCD will schedule the handler on the specific queue if it is not currently running, or -- more importantly -- coalesce pending events if it is. This provides excellent responsiveness without the expense of either polling or binding a thread to the event source.  Plus, since the handler is never run more than once at a time, the block doesn’t even need to be reentrant.
