Remove default persistent object cache

[ryan]

The persistent object cache is not enabled by default and is not actively maintained. Let's remove it. It can be resurrected as a third-party cache backend. The in-memory caching parts of cache.php should be retained.

includes/function.php still makes serialization calls, throwing a PHP memory error when it runs out of space.

That'd be due to options being set/updated, they *have* to be serialised if they're not a simple string. So by the sounds of it, Something is storing rather large options which overflows the memory limits?

reseting to 2.5 version. Infact, It'd be better to seek help in the support forums, or open a ticket which refers to your problem specifically. This ticket was for the removal of the cache, which doesnt affect you. (Assuming you're running an uptodate version of WordPress)
