Normally a timeout-free read is fine. Input comes, you process it, you go back to blocking on read. But in rare cases you may need to do an additional disambiguation read which should not block indefinitely.
Will have to see what Windows supports. select takes secs+micros. pselect takes secs+nanos. I don't see why anyone would need more than 1 second's worth of timeout which is an eternity in CPU time.
