Seeing the tests that rely on this method pass makes the issue in #147 all the more strange.

Actually, I would not be surprised if most of these tests are not validating where git decides to download the objects. If the parallel read tests end up download the same objects for each repo (in .git/objects) I'm not sure that they'd fail.
That could explain why #147 is still an issue, because that test specifically validates the shared cache folder was recreated.

Resolves #156.
See microsoft/git#205 for the Git code change. One race condition still existed: who creates the loose object directory first? The simple change is to check if the directory exists after the mkdir fails.
