Description:
------------
kill -TERM [php pid]

PHP CLI returns 0 rather than the expected 143 (128 + interrupt code). This is NOT the case for other interrupts, for example SIGINT results in return code 130 (128 + 2) as expected. 

I am not able to reproduce this in PHP 5. I can work around this by using the pcntl_signal handlers to correct the response codes, but this involves enabling ticks which is undesirable for my application. 

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

sleep(120);

#(interrupt this process with kill -TERM [pid])

Expected result:
----------------
Program return code 143 for SIGTERM. 

Actual result:
--------------
Program return code 0 for SIGTERM.
