memcached: updated to 1.6.7

Memcached 1.6.7

Overview

Mainly a bugfix release. -o resp_obj_mem_limit is deprecated, as the memory is all pooled from read_buf_mem_limit now. Almost all connection memory is now managed by this one tunable.

Fixes a bug preventing 1.6 series to work properly on OS X. Improves automated slab rebalancing for bursty writes.

Contains code refactors and fixes related to future work. Should not have any functional changes.
