Just wanted to add that if you do roll your own,
sock.fcntl(Fcntl::F_SETFL, Fcntl::O_NONBLOCK is available,
at least on the Unix platforms.

But indeed as has been discussed before, it'd be
***** OUTSTANDING ***** if ruby would just do
non-blocking I/O internally.

It seems even Windows sockets can be put into
non-blocking mode, via
ioctlsocket(sock, FIONBIO, ...)

I presume if it were utterly trivial for ruby to do
non-blocking I/O internally, it would have been done
long ago.  I know too little about ruby's internals
to guess why it's (apparently) difficult.  But it
would be very, very nice.
