Fix a grammar mistake; note what happens when the timeout is

    <p>The <code>WINCH</code> or <code>graceful-stop</code> signal causes

    the parent process to <em>advise</em> the children to exit after

    their current request (or to exit immediately if they're not

    serving anything). The parent will then remove it's <directive 

    serving anything). The parent will then remove its <directive 

    module="mpm_common">PidFile</directive> and cease listening on

    all ports. The parent will continue to run, and monitor children

    which are handling requests. Once all children have finalised

    and exited or the timeout specified by the <directive 

    module="mpm_common">GracefulShutdownTimeout</directive> has been

    reached, the parent will also exit.</p>

    reached, the parent will also exit.  If the timeout is reached,

    any remaining children will be sent the <code>TERM</code> signal

    to force them to exit.</p>

    <p>A <code>TERM</code> signal will immediately terminate the 

    parent process and all children when in the "graceful" state. However
