    I agree, but also notice that some of these syscalls, specially those
which are optimizations for certain situations like this one or
sendfile(), could also be used by the rest of python's core modules if
they're available. In this case in particular, it could be used to speed
up copyfile(), copy(), copy2() and probably copytree() from the shutil
module. In fact, if this patch goes in, I'm planning to implement such
optimizations.
