Memcached with OPcache

[ChristopherP]

Hi Christopher,

I did some before and after benchmarks on a mildly complex WordPress site. There was no significant difference in page load times.
So I'm following Dions advice, and not pursuing it.

So now I'm just waiting for Centos 7 and PHP-FPM

WebEndev, thanks for the update. I think I'll hold off on testing APCu.
