Description:
------------
NOTE: all of this happens when using PHP from the command line, don't know about other cases, that is harder to measure.

Using oci_connect with PHP 5.3.2 (or 5.3.1 or snap php5.3-201006161430) against Oracle 10.2.0.4 causes a PHP script to hang for about a second after all code has been run.  Script doesn't crash, just takes way too long to finish.

i.e. one can do something like this

 print "FIRST LINE OF CODE\n";
 oci_connect('user', 'pass');
 print "LAST LINE OF CODE\n";

and after "LAST LINE OF CODE" is printed, the program will hang for about a second, then finish.  If you remove the oci_connect line, the program runs without any post-code hangup.  PHP 5.2 on the same machine runs with no problems.

Note: the problem happens if the user/pass are correct or not.

What works and what doesn't against Oracle 10.2.0.4:

PHP 5.2              (oci8 1.2.4)     -> works fine
PHP 5.3.1            (oci8 1.3.5)     -> hangs for around one second
PHP 5.3.2            (oci8 1.4.1)     -> hangs for around one second
PHP 5.3-201006161430 (oci8 1.4.2-dev) -> hangs for around one second

What works and what doesn't against Oracle 10.2.0.3:

PHP 5.2              (oci8 1.2.4)     -> works fine
PHP 5.3.1            (oci8 1.3.5)     -> works fine
PHP 5.3.2            (oci8 1.4.1)     -> works fine
PHP 5.3-201006161430 (oci8 1.4.2-dev) -> works fine

Seems to be related to 10.2.0.4 and certain versions of PHP's oci8.

All these PHP's were built with the same configure line:
./configure --prefix=/opt/php --with-oci8 --with-apxs2=/opt/apache2/bin/apxs --enable-ftp --with-xmlrpc --with-iconv --with-curl --with-pear --enable-pcntl --with-zlib --with-readline

I have tested everyone of the above PHP's using 'php -n' (no php.ini).

Again, the bug only manifests on Oracle 10.2.0.4.

Test script:
---------------
<?php

#run this script from the command line with the 'time' command on linux, like so, to see the problem:
#
# time php -n myscript.php
#

print "before connect: ".microtime(true)."\n";

oci_connect('user', 'pass');

print "after connect: ".microtime(true)."\n";

#Note that the slowdown isn't bound to oci_connect,
#The two print statements will happen BEFORE the slowdown occurs,
#i.e. after all PHP code has been processed.

#using strace on the script with the '-c' is also interesting...

?>


Expected result:
----------------
I expect the script to complete in .05 to .15 seconds (or so).

Actual result:
--------------
Script takes at least a full second to finish, after all code has been executed.
