- Use multiple threads / database connections to:
1. Escape the transaction the spec seems to be running
in (`config.use_transactional_fixtures` is off, but
`ActiveRecord::Base.connection.open_transactions` is not empty
at the beginning of the spec.
2. Simulate a Sidekiq worker performing the hard delete outside of the
soft-delete transaction.
- The spec is a little clunky, but it was the smallest thing I could get
working - and even this took a couple of hours. Let me know if you
have any suggestions to improve it!
