Description:
------------
It appears that php_oci8.dll is not thread safe. We're trying to run PHP 5.1 in ISAPI mode using php_oci8.dll to connect to Oracle.

We can use ODBC instead of php_oci8.dll but this slows things down by as much as three times. We can also use PHP in CGI mode with php_oci8.dll but this also adversely effects performance.

I guess we're just looking for confirmation here. If it's a known issue that php_oci8.dll is not thread safe then we'll have to find another solution.

Reproduce code:
---------------
Any code will reproduce this. We are using phpinfo(). We are aware that phpinfo() leaks on purpose (not a bug) but for the purposes of this testing we're not concerned about memory leaks as the test only runs for 5 minutes.

Expected result:
----------------
Expect the web server not to crash during load test. 

Actual result:
--------------
Server crashes after 20 seconds with thousands of HTTP errors. Works perfectly in ODBC mode.

Works perfectly fine with threaded web-servers like Apache2.

Is IIS5 a threaded web server?

I guess so.
