Newbie: How ought I wrap a blocking network receive function?

<p>I&#39;ve got some code that sets up a signal handler and then blocks waiting for a notification to arrive (via github.com/iwanbk/gobeanstalk). What I&#39;m having trouble figuring out how to do is to wrap the blocking <code>beanstalk.Reserve()</code> so that I don&#39;t try to pull another job until I&#39;m finished processing the first one and that I pay attention to my signal channel so I can terminate the process.</p> <p><a href="http://pastebin.com/dY8ANV99" rel="nofollow">Here&#39;s a pastebin of the code</a> (I also would appreciate any stylistic or other commentary as I&#39;m still learning Go and realize I&#39;m bad at it still).</p>
