title: Understanding Devel::Leak
body: <p>Below is a piece of code I am using and its output.</p>
  
  <pre><code>my $handle;
  my $enterCount = Devel::Leak::NoteSV($handle);
  print "$date entry $enterCount";
  &lt;&lt;&lt;&lt; my piece of code &gt;&gt;&gt;
  my $leaveCount = Devel::Leak::CheckSV($handle);
  print "$date exit $leaveCount"; 
  </code></pre>
  
  <p>output:</p>
  
  <pre><code>1) 
  Mon 11/10 02:34:55 entry 383852
  Mon 11/10 02:35:03 exit 486726
  
  2) 
  Mon 11/10 04:00:31 entry 383852
  Mon 11/10 04:00:39 exit 493216
  
  3)
  Mon 11/10 04:05:15 entry 383852
  Mon 11/10 04:05:23 exit 493927
  </code></pre>
  
  <p>Every time I run my script the <code>$enterCount</code> value is same whereas the <code>$leavecount</code> values keeps on increasing. What dose this signify? Does it represent memory leak ? What exactly does it show?</p>
