TODO

* bug as shown with netcat (w/ small 16 byte object reproduces)

>>I've done the following script to check that memcached has a key in it's
>>inside, and thus know that it's working correctly:
>>echo -e "get is_ok\r\nquit\r\n" | netcat $host $ip
>>
>>and I find that sometimes it returns the VALUE in it's inside, but other
>>not.

* namespaces

* binary get protocol

* refresh/touch command.

* finer granularity of time for flush_all/delete, or generation number.

* slab class reassignment still buggy and can crash.  once that's
  stable, server should re-assign pages every 60 seconds or so
  to keep all classes roughly equal.  [Update: fixed now?, but 
  not heavily tested.  Future: make slab classes, with per-class
  cleaners functions.]

* calendar queue for early expirations of items, so they don't push
  out other objects with infinite expirations.

* curr_items never decreases?  mailing list report.

* memcached to listen on more than one IP.  mailing list request.
