Message11354

My usual development workspace on Linux (Mint 18 Cinnamon-64Bit) is hosted on an NTFS partition for better interoperability with Windows.
I observe test_dumbdbm and test_shutil to fail in this settings, while both pass if I move dist-folder to an ext4-partition. test_mailbox also suffers from this, but also fails for me on ext4 with less failures though. On Windows I don't observe any of these failures, but maybe they are just skipped (didn't yet check).

Outputs on NTFS are as follows:
