            Is this still open? Is there a repro?

            This is still an issue, to see the problem you can run wtperf like:

            $ WIREDTIGER_CONFIG="statistics=[all],statistics_log=(wait=10)" ./bench/wtperf/wtperf -O ../bench/wtperf/runners/medium-btree.wtperf
            		 
            $ grep "tracked bytes belong" WT_TEST/WiredTigerStat.*

            It will show a set of values that don't make sense. I've got a change in progress to fix the tracking.
