Attachment: patch-1140-3.txt
Patch incorporating review comments.
bq. I would enhance testReferenceCount to add 3 files instead of 2, the first
file should be localized correctly, the second should fail after the reference
count is incremented, and the third will not be localized at all. Then we can
verify that the reference count for all files is 0.
I enhanced the test to add three files where first file would fail in
localization, second file is already localized by a different job and third
file is never localized. The path to verify successful localization is already
covered.
> Per cache-file refcount can become negative when tasks release
> distributed-cache files
