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