      Since SERVER-29277, the dropDatabase waits for all collection drops to complete before removing the entry for the database from the catalog. To do this, the free function mongo::dropDatabase() needs to call either ReplicationCoordinator::awaitReplicationOfLastOpForClient() or ReplicationCoordinator::awaitReplication(). However, these functions fail when dropDatabase() is called from within an applyOps operation because applyOps executes all its given operations while holding the global lock.

      To reproduce:

      db.adminCommand({applyOps: [{op: 'c', ns: 'test.$cmd', o: {create: 't'}}, {op: 'c', ns: 'test.$cmd', o: {drop: 't'}}, {op: 'c', ns: 'test.$cmd', o: {dropDatabase: 1}}]})
