Merge pull request from takluyver/import-performance Import performance Defer various imports for a small reduction in startup time. IPython.lib.__init__ previously loaded IPython.lib.inputhook to export some of its functions. This meant that importing anything from IPython.lib also loaded inputhook. For now, I've just removed that import, but that is an API change, because the functions are no longer accessible as e.g. IPython.lib.enable_qt4 Added a note about the API change. Timing command, borrowed from Openoffice to simulate cold start: $ sync ; echo 3 | sudo tee /proc/sys/vm/drop_caches; time ipython3 -c pass Results with this branch: 7.68, 7.64, 7.35, 7.38 s 'real' Results with master: 8.17, 8.04, 7.81, 7.77

      """ Simple TCP socket server that executes statements in IPython instance.

      Usage:

      import ipy_server

      ipy_server.serve_thread(16455)

      Now, to execute the statements in this ipython instance, open a TCP socket

      (port 16455), write out the statements, and close the socket.

      You can use e.g. "telnet localhost 16455" or a script to do this.

      This is a bit like 'M-x server-start" or gnuserv in the emacs world.
