in progress with adding connection in both Client and Server
finish coding; ready for test
end of Mar 11
fixed bugs; working code for connection; move on for more test on connection_1
reconnect to server when reuse a conn
commit b4 checking old branch
fixed problem with closing conn: an optimization in processResponse() when there's only 1 call in the queue. That one didn't close connection. And a conn should be closed on both sides.
profiled with valgrind (leak check, massif), gprof; analized queuing
commit everything
