+     As of PHP 4.3.0 PCNTL uses ticks as the signal handle callback mechanism,
+     which is much faster than the previous mechanism. This change follows the
+     same semantics as using 
+     "<link linkend="control-structures.declare.ticks">user ticks</link>". You
+     must use the <link linkend="control-structures.declare">declare()</link>
+     statement to specify the locations in your program where callbacks are
+     allowed to occur for the signal handler to function properly (as used in
+     the above example).
