Would I wrong in assuming that exit; or die(); would properly kill the program in your situation?

Well, that figures. Its way too simple a test to have slipped through your regression testing.
I have other programs that are more complicated which fail in exactly the same way. In all cases,
absolutely all of the work, whatever it is, gets done to completion. All that happens is they hang
on exit or when the code falls through the end of the script.
It sounds like one of those exec/wait problems whereby the wait in a mother task fails to complete
when the daughter task, that's doing all of the work, ends. This could easily be OS-dependent
or build-dependent and, hence, hard for you to reproduce.
If you want to contact me offline about where to look, I'll try to debug the problem on the
test system where its failing.

I can't reproduce it.

Description:
------------
Scripts executed under the CLI never end. For example, the following test script will run as long
as you let it, until it is killed. It doesn't appear to be looping, as it consumes no
resources. Rather, it appears to be blocked waiting for some signal that never happens.
Note that this may explain why the 5.4.3 build cannot be built with "--enable-phar" and
why "make install" hangs forever at the end.
Build parms: ./configure --with-apxs2=/usr/share/httpd-2.4/bin/apxs --with-curl --with-gd
--with-ldap --with-libxml-dir=/usr/local --with-mcrypt --with-mysql=/usr/local/mysql
--with-mysqli=/usr/bin/mysql_config --with-openssl --with-pspell --with-unixODBC=/usr/local/unixODBC
--enable-bcmath --disable-phar --enable-sockets
Test script:
---------------
#!/usr/bin/php
<script language="php">
fwrite(STDOUT, "This is a test\n");
</script>
Expected result:
----------------
The CLI program exits.
Actual result:
--------------
The CLI program never exits.
