Description:
------------
Hello,

The APCu extension for user caching seems to be incompatible with Windows servers using IIS, PHP as FastCGI and multiple application pools.

Configuration:

Windows Server 2012
IIS 8.0
FastCGI
PHP 5.4.13 x86 NTS VC9
APCu extension 4.0.0 x86 NTS VC9 for PHP 5.4 (php_apcu-4.0.0-5.4-nts-vc9-x86.zip)
One IIS application pool per website
One FastCGI application (php-cgi.exe) per website

Test script:
---------------
APCu runs very well if you use it with only one website but if you use it with multiple application pools an HTTP 500 error is returned by IIS.

I think that when multiple application pools or multiple FastCGI applications are used, multiple simultaneous instances of APCu can't be created.

Original APC extension has probably the same problem (not tested).

With PHP 5.5 and integration of OPcache extension, the Microsoft WinCache extension will be probably stopped. So please, offer also to Windows users a solution for user caching.

Thanks.
