server1.rb
-------
require 'socket'

ssc = TCPServer.new '', 9989
sc = ssc.accept

p sc.recv(1024)

p sc.recv(1024)
# ruby 2.0.0p0: has OOB data, not return until remote send data again or close
p sc.recv(1024, Socket::MSG_OOB) 

p sc.recv(1024, Socket::MSG_OOB | Socket::MSG_PEEK)
p sc.recv(1024, Socket::MSG_OOB)
p sc.recv(1024)


------
client1.rb
-------------
require 'socket'

sc=TCPSocket.new '127.0.0.1', 9989

sc.send '1234', 0
sleep 1.5

sc.send 'abcd', Socket::MSG_OOB
sleep 3

sc.send 'EFGH', Socket::MSG_OOB
sleep 1.5

----------------

Use ruby 2.0.0p0 run above server1 code, output is
"1234"
"abc"
"dH"
""
""
"EFG"
,
use ruby 1.9.3p327 or python or c code, output is
"1234"
"abc"
"d"
"H"
"H"
"EFG"


Is this has a bug?
