This module is an interface to the new splice()/tee()
system calls under Linux Kernel 2.6.17 and higher.
Splice allows one to transfer data from a stream to
another within the kernel, without need for user-land
involvement, while tee transfers data from a pipe to
another without consuming the data on the first pipe.
By combining both system calls, it is possible to
actually do zero-copy movement of data from one or many
sources to many destinations.

call mechanisms :

We would like to know if this is worth for inclusion in
the standard Python distribution? What should be
modified to make it more "compliant" to the python
rules? This file will probably need to be updated to
conform to python style standards.
