It sounds simple but doesn't work. If select tells you a file
descriptor doesn't have data waiting you can't be sure there isn't
still data in the corresponding channel's buffer. See the thread that
I referenced for a good discussion of why this is annoying. For one
thing, it makes it impossible to use Marshal.from_channel without
potentially blocking.
