Serhiy Storchaka added the comment:

Test should be marked with dry_run=False, otherwise it is false passed. Allocation of growing buffer needs extra memory, in my experiments memuse=2.5 is enough. And I think this test should require the largefile resource. Here is a patch. It also significantly speeds up a test on Linux.
