Comment:

 With `async` set, do we need to worry more than usual about data
 corruption?  According to [http://nfs.sourceforge.net/#faq_b6 this Linux
 NFS FAQ], `async` is potentially unsafe.

 Should we do as Craig suggests above, e.g., `pass` in the `except` block
 if `dirname` now exists, but `raise` otherwise?
