<h3>Summary</h3>

    <p>The Server consists of a main, parent process and a small, static
    number of child processes.</p>

    <p>The parent process's job is to manage the child processes. This
    involves spawning children as required to ensure there are always
    <code class="directive"><a href="../mod/mpm_common.html#startservers">StartServers</a></code> processes
    accepting connections.</p>
    
    <p>Each child process consists of a a pool of worker threads and a
    main thread that accepts connections and passes them to the workers via
    a work queue. The worker thread pool is dynamic, managed by a
    maintenance thread so that the number of idle threads is kept between
    <code class="directive"><a href="../mod/mpm_common.html#minsparethreads">MinSpareThreads</a></code> and
    <code class="directive"><a href="../mod/mpm_common.html#maxsparethreads">MaxSpareThreads</a></code>.</p>
