# This function sometimes writes sometimes blocking-reads from lists/sorted
# sets. There are multiple processes like this executing at the same time
# so that we have some chance to trap some corner condition if there is
# a regression. For this to happen it is important that we narrow the key
# space to just a few elements, and balance the operations so that it is
# unlikely that lists and zsets just get more data without ever causing
# blocking.
