Don't trust code you find on newsgroups. :o) You have to check the
returned value first. According to documentation, it can return
Socket.ERROR:

Can you show with complete code? Perhaps the stream is in blocking mode?

Posix read(2) man page says
"It is not an error if this number is smaller than the number of bytes
requested; this may happen for example because fewer bytes are actually
available right now (maybe because we were close to end-of-file, or because
we are reading from a pipe, or from a terminal), or because read() was
interrupted by a signal."
