+<usage>
+    <p>If Apache httpd and APR are built with thread support, the health check
+       module will offload the work of the actual checking to a threadpool
+       associated with the Watchdog process, allowing for parallel checks.
+       The <directive>ProxyHCTPsize</directive> directive
+       determines the size of this threadpool. If set to <code>0</code>, no threadpool
+       is used at all, resulting in serialized health checks. The default size is 16.</p>
