Tweak the 'load balancing' algorithm
In order to reduce contention we randomly skipped jobs, but this
caused many jobs to end up stopping early. Now instead we keep on
going until we time out (also increased the chance of doing work).

# Performance note: I benchmarked this code using a set instead of
# a list for the stopwords and was surprised to find that the list
# performed /better/ than the set - maybe because it's only a small
# list.
