You should:
  1. write the issue in the message body
  2. what you needed/wanted/expected and actually what occured

I ran it and got results I expected.  That is:

    # on some term:
    >ruby <<EOS
    require 'socket'
    server = TCPServer.new('127.0.0.1',5190)
    while (session = server.accept)
      begin
        thisUser = session.gets
        thisUser = thisUser.scan(/<user>(.*?)<\/user>/).to_s
    
        session.print "<userlist>#{thisUser}</userlist>\0"
    
      ensure
        session.close if session
        #puts "sesson closed"
      end
    end
    EOS
    
    # and on the other:
    >telnet localhost 5190
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.
    <user>foo</user>
    <userlist>foo</userlist>Connection closed by foreign host.


I doubt your undisclosed client code doesn't send "\n" and so the
server is waiting for "\n" on IO#gets, but it's just a my guess.
