title: Abnormal behavior of log4go
body: <p>I found the <a href="http://code.google.com/p/log4go/w/list" rel="nofollow">log4go</a> package loses logs from time to time.</p>
  
  <p>Following is a simple code snippet(I moved the <code>log4go</code> directory so the following import is ok.):</p>
  
  <pre><code>package main
  import (
      "log4go"
      "log"
      "fmt"
  )
  
  func main() {
      fmt.Println("fmt")
      log.Println("log")
      log4go.Info("log4go")
      log4go.Info("log4go")
  }
  </code></pre>
  
  <p>Then I executed it by <code>go run test.go</code>, and the output is as follows:</p>
  
  <pre><code>fmt
  2013/01/10 15:24:04 log
  </code></pre>
  
  <p>The messages by <code>log4go</code> are not written to output.</p>
  
  <p>Why?</p>
