This release fixes issue #1864, where some simple tests would perform
very slowly, because they would run many times with each subsequent
run being progressively slower. They will now stop after a more
reasonable number of runs without hitting this problem.
Unless you are hitting exactly this issue, it is unlikely that this
release will have any effect, but certain classes of custom generators
that are currently very slow may become a bit faster, or start to
trigger health check failures.
