FYI: The attached SVN patch was committed to:

• trunk rev.
• 4.4 rev.
• 4.3 rev.

Type: bug / cleanup

BT: http://bugs.typo3.org/view.php?id=16582

Problem:
The caching framework example configuration for memcached in config_default is misleading:

• Memcache cache backend should be used with care, the default dbbackend is a better choice in most real live use cases
• A documentation of the caching framework options must not be buried in this file but should be done with an official documentation at a central place
• The given example is incomplete and leads to thrown exceptions

Solution:
Remove it.
