object deletion

[Steven Grimm]

What's the problem you're trying to solve? You want to see why cache 
entries are vanishing, I imagine? If so, then you're right, just logging 
it will be easiest, especially if you have multiple clients. The server 
doesn't do that out of the box, but it'd be pretty easy to hack in. I 
think the following would do it (output will only happen if you run the 
server with "-vv"):

--- a/src/items.c
+++ b/src/items.c
@@ -100,6 +100,8 @@ item *do_item_alloc(char *key, size_t nkey, int 
flags, rel_time_t expti
 
         for (search = tails[id]; tries>0 && search; tries--, 
search=search->prev) {
             if (search->refcount==0) {
+                if (settings.verbose > 1)
+                    printf("evicting item %s\n", ITEM_key(search));
                 do_item_unlink(search);
                 break;
             }

That's against the MT version of the code but should apply to the 
vanilla 1.2.x code too (maybe even 1.1.x).
