FWIW, I've counted seven 006_transfer_modes failures happened during this
year. Five are from Windows animals:

And two from culicidae, which tests EXEC_BACKEND and thus suffers from [1]

Probably, this number could justify improving the test so that we can
identify the failure reason for sure looking at the upgrade logs. As of
now, we can only guess it, based on the animals' specifics...
