  75 <usage>
  76     <p>The <directive>MaxRequestsPerThread</directive> directive sets
  77     the limit on the number of requests that an individual server thread
  78     will handle. After <directive>MaxRequestsPerThread</directive>
  79     requests, the thread will die. If <directive
  80     >MaxRequestsPerThread</directive> is <code>0</code>, then the thread
  81     will never expire.</p>
  82
  83     <p>Setting <directive>MaxRequestsPerThread</directive> to a
  84     non-zero limit has two beneficial effects:</p>
  85
  86     <ul>
  87       <li>it limits the amount of memory that a thread can consume
  88       by (accidental) memory leakage;</li>
  89
  90       <li>by giving threads a finite lifetime, it helps reduce
  91       the number of threads when the server load reduces.</li>
  92     </ul>
  93
  94     <note><title>Note:</title>
  95       <p>For <directive module="core">KeepAlive</directive> requests, only
  96       the first request is counted towards this limit. In effect, it
  97       changes the behavior to limit the number of <em>connections</em>
  98       per thread.</p>
