No, that's not right -- a read of more than 0 bytes will
always block until at least 1 byte is available, or
something happens that counts as an EOF condition.
However, with some devices it's possible for what
counts as EOF to happen more than once, e.g. ttys.
Sorry, you're absolutely right. I was thinking only of the fact that
read() at EOF is not an error, rather than the blocking behaviour. It
sounds like Python read() really is very similar to Unix read() in
behaviour.
