Description:
------------
No more received the signal HUP after using pcntl_exec

Test script:
---------------
#!/bin/php
<?php

function sig_handler()
{
    echo "sig_handler() called\n";
    pcntl_exec( "/test.php" );
}

echo "set signal\n";
pcntl_signal( SIGHUP, "sig_handler" );

while ( 1 ) {
  pcntl_signal_dispatch();
  sleep(1 );
}

?>

Expected result:
----------------
first kill -HUP PID
show :
sig_handler() called

do a second kill -HUP PID
and show :
sig_handler() called

Actual result:
--------------
first kill -HUP PID
show :
sig_handler() called

do a second kill -HUP PID
and nothing append and no more possible to do a CTRL+C on the program

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

pcntl_exec replaces the current process, try exec instead.
