No. That's stupid. It's useless. By 'would not block' they mean 'if
nobody else messes with the descriptor, the operation would not block.'
Your meaning means that select is absolutely *useless* to a programmer
unless the socket is set to non-blocking mode; there is no mention in the
select manpage that the socket must be in non-blocking mode. Further,
since a non-blocking selectd can return EWOULDBLOCK for any operation,
select on non-blocking becomes nothing more than an optimization hint to
avoid a read system call.
