    Description

      If a node is stepping down in multiple threads at once, one thread can lag behind the other stepdown thread and still be running when the node starts applying oplog entries as a secondary. In this case, if the remaining stepdown thread still has ScopedBlockSessionCheckouts in scope, it will block checking out sessions, which could cause us to fail to apply a commitTransaction oplog entry, ultimately triggering this fassert.
