Patch 8.1.0921
Problem:    Terminal test sometimes fails; using memory after free.

DENNIS: Oh, very nice. King, eh!  I expect you've got a palace and fine
        clothes and courtiers and plenty of food.  And how d'you get that?  By
        exploiting the workers! By hanging on to outdated imperialist dogma
        which perpetuates the social and economic differences in our society!
