title: Signal Dispositions in Pthreads
body: <p>The <code>man</code> page for <code>pthreads</code> mentions:</p>
  
  <pre><code> POSIX.1 also requires that threads share a range  of  other  attributes
         (i.e., these attributes are process-wide rather than per-thread):
  
         ...
  
         -  signal dispositions
  
         ...
  </code></pre>
  
  <p>What do "signal dispositions" mean? </p>
