Increase length of tests to increase probability of hitting a bug.
Shrink deletes to reads if possible (simplifies interpreting failed tests)
Wait before stabilizing, to make sure conflicts have a little time to appear.
usort the possible states! How could we forget to do this? We're collecting many duplicates.
Added ?SOMETIMES(2,...) so that we don't start trying to shrink tests that are unlikely to fail again.
Run ALL tests 3 times (inside the ?SOMETIMES), so that we still detect tests that fail unpredictably, as long as they fail pretty often.
Did I change interesting-tests?
