I suggest you find a good authoritative source for your claim
that select() should not be used with blocking sockets.
http://man7.org/linux/man-pages/man2/select.2.html
Section BUGS:
"Under Linux, select() may report a socket file descriptor as "ready
for reading", while nevertheless a subsequent read blocks. This could
for example happen when data has arrived but upon examination has
wrong checksum and is discarded. There may be other circumstances in
which a file descriptor is spuriously reported as ready. Thus it may
be safer to use O_NONBLOCK on sockets that should not block."
Authoritative enough for you?
That must be a recent change then. But certainly that is a bug
in Linux select, not in programs relying on the (long time)
documented correct behavior.
Enjoy
