On implementing a memcached clone in Node.js

Have a hankering to implement one of the standard daemons, like memcached, in Node.js?  Here's an example of implementing memcached with Node.js available on github at https://gist.github.com/3244607.  See this discussion thread for more:- https://groups.google.com/forum/?fromgroups#!topic/nodejs/gqZZmMf3W5M

One suggestion from the discussion thread is to add --nouse-idle-notification to the invocation.
