title: Output from benchmem
body: <p>I see following output when running benchmarking with memory profiler</p>
  
  <pre><code>SomeFunc             100      17768876 ns/op         111 B/op          0 allocs/op
  </code></pre>
  
  <p>I don't understand the output - 0 allocs/op but there are 111 B allocated? Any idea what it means? Does my function allocate memory on heap or not?</p>
