Subject: Socket hangs when I read after writing!

    I have the following Ruby program:


sock = TCPSocket.new('host.com', 12345)

sock.write('This is a test')

data = sock.read(1024)
puts data


    ...The service this connection connects to just reads the string and 
write a response which this program then tries to read.  I expected it to 
just work but instead it just hangs.  The weird part is that it hangs before 
the data is actually written out through the socket.  The service on the 
other end doesn't get any data.  If I remove the end part of the program 
that attempts to read the response, the data makes it through and is read 
correctly by the service.
    What is wrong with my program?  Why is it hanging?
    Thank you...
