have been removed, you will not be able to use

+ <div class="note"><p>The <code>graceful-stop</code> signal allows you to run multiple
+ identically configured instances of <code class="program"><a href="./programs/httpd.html">httpd</a></code> at the
+ same time. This is a powerful feature when performing graceful
+ upgrades of Apache, however it can also cause deadlocks and race
+ conditions with some configurations.</p>
+
+ <p>Care has been taken to ensure that on-disk files
+ such as the <code class="directive"><a href="./mod/core.html#lockfile">Lockfile</a></code> and <code class="directive"><a href="./mod/mod_cgid.html#scriptsock">ScriptSock</a></code> files contain the server
+ PID, and should co-exist without problem. However, if a configuration
+ directive, third-party module or persistent CGI utilises any other on-disk
+ lock or state files; care should be taken to ensure that multiple running
+ instances of <code class="program"><a href="./programs/httpd.html">httpd</a></code> do not clobber each others files.</p>
+
+ <p>You should also be wary of other potential race conditions, such as
+ using <code class="program"><a href="./programs/rotatelogs.html">rotatelogs</a></code> style piped logging. Multiple running
+ instances of <code class="program"><a href="./programs/rotatelogs.html">rotatelogs</a></code> attempting to rotate the same
+ logfiles at the same time may destroy each other's logfiles.</p></div>
