It's a monkey-patch. Once this module is loaded, we know that we have a up-to-date view of the DB when we start a transaction.

Here is a place where it's important for us to have such behaviour:
  https://lab.nexedi.com/nexedi/erp5/blob/f6d96c460323a5b7094feff2fbbf545deb9195db/product/CMFActivity/Activity/SQLBase.py#L497

To check this, we also have a unit test at
  https://lab.nexedi.com/nexedi/erp5/blob/f6d96c460323a5b7094feff2fbbf545deb9195db/product/ERP5/tests/testInvalidationBug.py#L93
