When releasing the handle, alpm tries to do some self clean up by freeing the databases and transaction.
However, databases refuse to unregister is there is an in progress transaction. Causing them to leak if the handle is released while a transaction is active.
So... I've been sitting on this for a while. It does not seem the right answer to the issue to me. But I am not sure what the right answer is! Suggestions inline below.

Could we do an alpm_trans_release() here if handle->trans is non-null and abort if that fails?

This needs to stay. It is unexpected that _alpm_handle_free does not free its whole memory.
FREE(handle->root); FREE(handle->dbpath); FREE(handle->dbext);
