Appears to timeout while running callbacks

[etherbob]

We have some models with after_commit callbacks around ActiveStorage and some other external interactions that appear to be running after the data migration has completed. In the case of the ActiveStorage attachments they get cut off and raise exceptions. We don't get this behavior if we run the same code from a rake task or in the console.

We're on rails 6.1.4.1 and the latest pub release of the data-migrate gem.

adding disable_ddl_transaction! to the migration runs each commit and it's callbacks inside the transaction and was good enough for us, even if we miss the all-or-nothing nature of a wrapping transaction.
