Comment #1 on issue 183 by jhpark...@gmail.com: Reclaiming the space of  
flushed items is needed.
http://code.google.com/p/memcached/issues/detail?id=183
There is one more place in do_item_alloc() that the flushed items should be  
reclaimed.

        for (search = tails[id]; tries > 0 && search != NULL; tries--,  
search=search->prev) {
            if (search->refcount == 0) {
#if 1 // NEW CODE
                if ((search->exptime != 0 && search->exptime <  
current_time) ||
                    (search->time < settings.oldest_live &&  
settings.oldest_live <= current_time)) {
                    itemstats[id].evicted++;
                    itemstats[id].evicted_time = current_time -  
search->time;
                    if (search->exptime != 0)
                        itemstats[id].evicted_nonzero++;
                    STATS_LOCK();
                    stats.evictions++;
                    STATS_UNLOCK();
                } else {
                    itemstats[id].reclaimed++;
                    STATS_LOCK();
                    stats.reclaimed++;
                    STATS_UNLOCK();
                }

#else
                if (search->exptime == 0 || search->exptime > current_time)  
{
                    itemstats[id].evicted++;
                    itemstats[id].evicted_time = current_time -  
search->time;
                    if (search->exptime != 0)
                        itemstats[id].evicted_nonzero++;
                    STATS_LOCK();
                    stats.evictions++;
                    STATS_UNLOCK();
                } else {
                    itemstats[id].reclaimed++;
                    STATS_LOCK();
                    stats.reclaimed++;
                    STATS_UNLOCK();
                }
#endif
                do_item_unlink(search);
                break;
            }
        }
