Examples:

# HTTP calls within transaction
User.transaction do
  user = User.new(user_params)
  user.save!
  # HTTP API call
  PaymentsService.charge!(user)
end

#=> raises Isolator::HTTPError

# background job
User.transaction do
  user.update!(confirmed_at: Time.now)
  UserMailer.successful_confirmation(user).deliver_later
end

#=> raises Isolator::BackgroundJobError
