[New-bugs-announce] [issue30749] Non-atomic and unusual (wrong) rename behavior under OS X, Python 2.7.13

[Alex Groce]

New submission from Alex Groce:

Attached file causes a failed rename, which is fine.  However, after the failed rename, the directory structure has changed (and the error reported is not very helpful).  Behavior does not match Linux or Windows behavior.

Discovered using random testing to check pyfakefs for conformance with os module, using TSTL tool.
