Using the 'splice' syscall from Python, in this demonstration to transfer the output of some process to a client through a socket, using zero-copy transfers. See 'splice.py'. Usage: 'python splice.py' in one console, then e.g. 'nc localhost 9009' in another. 'nonblocking.py' is a demonstration of using 'splice' with non-blocking IO.

Lots of code is similar to 'splice.py', take a look at that module for more
