If you do that, what do you do if available() returns false?  All Rick
wants to do - I suspect - is do nothing until either the read becomes
available or told to quit (e.g. a timeout or another channel event).

Using available() means setting up a polling loop - which is not nice!

What Rick needs - I suspect - is an ALT, which waits passively for
the read or quit event.
