Anybody really care for it?
I think it's too painful to support completely due to the way
SPLICE_F_NONBLOCK is handled for pipes and how the file O_NONBLOCK flag
of the non-pipe is relied on.
splice() ignores O_NONBLOCK on the pipe, instead relying on
SPLICE_F_NONBLOCK being passed to it. However, SPLICE_F_NONBLOCK
only affects pipes, so if you splice a pipe to a socket, you need
O_NONBLOCK on the socket.
Since MRI 1.8 uses non-blocking I/O and select() to schedule
threads, this is painful to deal with for users that may want
to see :EAGAIN or Errno::EAGAIN in some cases and not others.
Hopefully the above explaination is halfway coherent, I really
don't care enough about MRI 1.8 to do a better explanation :<
It may incidentally work in some/most cases, but 1.8 really isn't
worth my effort to maintain...

I plan to use io_splice in my Ruby server in a future, but my code
just works on Ruby 1.9 so.... :)
It's time to drop 1.8.
