 Makes the default hashing algorithm for keys use MD5. The value can be set to either MEMCACHED_HASH_DEFAULT, MEMCACHED_HASH_MD5, MEMCACHED_HASH_CRC, MEMCACHED_HASH_FNV1_64, MEMCACHED_HASH_FNV1A_64, MEMCACHED_HASH_FNV1_32, MEMCACHED_HASH_FNV1A_32, MEMCACHED_HASH_KETAMA. The behavior for all hashes but MEMCACHED_HASH_DEFAULT is identitical to the Java driver written by Dustin Sallings.

+Using this you can enable different means of distributing values to servers.
+The default method is MEMCACHED_DISTRIBUTION_MODULA. You can enable
+consistent hashing by setting MEMCACHED_DISTRIBUTION_CONSISTENT. 
+Consistent hashing delivers better distribution and allows servers to be 
+added to the cluster with minimal cache losses.

+=item MEMCACHED_BEHAVIOR_BUFFER_REQUESTS
+
+Enabling buffered IO causes commands to "buffer" instead of being sent. Any
+action that gets data causes this buffer to be be sent to the remote
+connection. Quiting the connection or closing down the connection will also
+cause the buffered data to be pushed to the remote connection.
