I can't imagine that even forking would help you here—your OS will still 
be performing only one I/O call at a time. Unless you've got an OS 
that's doing some funny optimization like aggregating filesystem 
metadata changes, you won't see any speedup. And that would be a strange 
thing to optimize for.

Multiprocessing generally only helps when your application is CPU bound, 
not I/O bound.
