I got excited by the title, but this all seems to be able giving 
non-filesystems a file-system like API.

If I've missed something, please let me know, but I couldn't find an 
async interface for writing to actual file systems. It feels like 
Twisted has just punted on them as "fast enough" to not need async 
interfaces, but that can really not be the case for networked 
filesystems (NFS, GPFS, etc) where the blocking time for reading or 
writing can be seconds (or minutes if it's having a bad day!).

What's the Twisted solution for these kinds of things? Defer all file IO 
into a thread?
