No, select on a read descriptor returns successfully when the descriptor
is "ready" to read, whatever that means. It normally means that a read
on the descriptor would not block (even if O_NONBLOCK is not set). Reads
of EOF satisfy this condition. This is normally the correct behaviour.
E.g., it prevents programs reading stdin via select() loop from hanging
when stdin is a pipe with no writers.
