      In SERVER-22906 (among others), we recommend turning on tcmalloc's aggressive decommit feature, which we have disabled by default (overriding current tcmalloc's default).

      There are performance test regressions, we need to understand them and figure out if anything can be done to reduce the impact. Then we need to make a cost/benefit decision.
