Yes, it is basically the same problem as the buffer cache. Excessive single-use patterns dirty the small cache or require a too big cache to be usefull. Maybe a user specific limit of percentage of hash (and locks) used? I mean the untar test case is a bit synthetic, but think of concurrent read access in a cluster of nntp servers (news article pool).
