createDirectoryIfMissing does not fail on unwritable parent dir
On OSX, using createDirectoryIfMissing to create a new directory inside a directory for which we do not have write permissions does not throw any exception. Of course it should throw an exception, as it does under Linux.
$ mkdir unwritable
$ chmod ugo-w unwritable
$ ghci
> System.Directory.createDirectoryIfMissing True "unwritable/tst"
>On OSX (10.9.2) this does not fail. Under Linux (albeit with 7.6.3) this does throw an exception as expected:
