We recently removed the lookaside file from WiredTiger as durable history replaces it. MongoDB relies on a particular statistic to make decisions about how much cache pressure WiredTiger is experiencing. We removed that statistic, and will need to update MongoDB prior to merging this change there, so it no longer uses the stat.
