Found this solution by Wes Gamble (thanks Wes) that seems to work...
"http://www.ruby-forum.com/topic/100121#215541"
But I have to say, it seems antithetical in a Rails app. I don''t
necessarily think this is a memcache_client issue. I have another app
that uses memcache_client and I''ve not had any issue like this - very
curious.
