Just to clarify things since I helped write the initial blog post about twemcache... in our original post, we had an error regarding the slab calcification problem we mentioned, this problem ONLY applied to our v1.4.4 fork of memcached. After speaking with the upstream maintainers, we learned that recent memcached versions have addressed some of these problems. These are the type of conversations we want to have. At the time we adopted memcached, that's the version we went with and made sure it worked well in our production environment as we scaled as a company.

For example, this is also how we treat our work with our MySQL fork [https://github.com/twitter/mysql] which we maintain in the open and have signed an OCA with Oracle to help get work pushed upstream so everyone benefits in the long run.
In Twitter says they fixed the Memcache calcification problem. Dormando disagrees.
