I think asyncio would be better off using os.sendfile() / TransmitFile directly, in fact the current patch explicitly does not support non-blocking sockets (I couldn't see any sane approach to do that). Here's an example of how os.sendfile() should be used in an async manner: https://code.google.com/p/pyftpdlib/source/browse/tags/release-0.7.0/pyftpdlib/ftpserver.py#1035 asyncio should be doing something very similar to that and do the necessary stuff so that you can "yield from transport.sendfile(file)". Actually I can see what I can do in that regard after I'm finished with this.
