Separate apc-caches for each fpm-pool

Hi, all Not to get the bugfix https://bugs.php.net/bug.php?id=57825 too much off-topic, I write this question in the mailinglist here: Taking the case I have two fpm-pools on different sockets - the first pool is responsible for www.example1.com and the second one for www.example2.com. If www.example1.com has 4 workers, they're all using the same apc-cache. That's absolutely as expected. But also the workers of www.example2.com are using this cache. In my opinion it would be nice if the pools would have a separate cache. I now found a solution for this: Just use more than one fpm-master that is controlling the pools. (http://groups.drupal.org/node/198168) Is this the way to go, or do you know of another way? Should this be added to the APC- or fpm-documentation or is it enough that you can find f.e. it using Google, if you need it? Bye Simon
