Xcache issues: Apache Segfaults when caching, need to unserialize the serialized data

I setup authcache to work with xcache and got the "white screen of death" after the first load of any page. Checking the apache logs showed that processes were ending due to segfaults.

Seeing as authcache is a fork of Cache Router i searched their forum and found this thread: http://drupal.org/node/341575.

Xcache can not store objects in the variable cache. I am attaching a patch that typecasts $cache into an array before making the xcache call.

The attached patch fixes the error above. The patch also unserializes the data being pulled back from xcache so that it can be used by Drupal.
