Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
If you do a session_start() the session file is locked till the session is
closed again. This is needed to avoid loosing data from concurrent requests. In
your example: If 2.php would change the session data this would be overwritten
by the old state in 1.php.

Description:
------------
On RHEL(or Centos) 5.6 running any available PHP package thru RedHat and the
latest version of PHP (5.3.6).
Run first script provided in a browser, then while that is running, fire up the
second script. The second script will not finish until the first one calls the
session_write_close() function.
Test script:
---------------
=== 1.php ===
<?php
$counter=1;
$DB= mysql_connect(localhost,$user,$pass,true);
mysql_select_db("database");
session_start();
echo "Starting...\n";
while ( $counter <= 5 )
{
echo "$counter ... \n";
sleep(2);
$counter++;
}
echo "Done!... \n";
session_write_close();
?>
=== 2.php ===
<?php
session_start();
echo "TESTING!\n";
session_write_close();
?>
Expected result:
----------------
When both scripts are run at the same time, the second script should exit
(nearly) immediately after opening a session, echoing the TESTING line, then
closing the session. After the while loop is done in the first script, it
should exit as expected.
Actual result:
--------------
When the both scripts are executed at the same time (or one right after the
other), the second script hangs at the 'session_start()' line until the first
script is done.
