 Linear search is under control and number of dst entries very high but very
 constant at the cost of calling GC a number of times second. But I don't 
 understand why we do not see any GC ignored. Did you ever write to 
gc_min_interval 
 in proc? Never seen rtstat's like this but it seems to do the job.
