title: How do I halt the continuing in GDB
body: <p>I'm pretty much using GDB for the first time.
  I run</p>
  
  <pre><code>$ gdb
  </code></pre>
  
  <p>then I'm running</p>
  
  <pre><code>attach &lt;mypid&gt;
  </code></pre>
  
  <p>then I see that my process is stuck (which is probably ok). Now I want it to continue running, so I run</p>
  
  <pre><code>continue
  </code></pre>
  
  <p>and my process continues running
  but from here I'm stuck if I want again to watch my current stack trace etc. I couldn't get out of continuing... I tried <kbd>Ctrl</kbd>-<kbd>D</kbd> etc. but nothing worked for me... (was just a guess).</p>
