Comment:

 I'm getting closer to tomeu's perspective on this.  Attaching a file that
 will do the lazy importing...now if we could only figure out where to put
 it :).

 I've had a play with sugar-toolkit/activity/activity.py and Terminal-
 activity/terminal.py and I don't think we're going to get more than a
 second or so out of lazy importing.

 To use, here's an example of some changes to terminal.py that I tried:
 {{{
 import time
 t0 = time.time()

 from lazyimport import lazyModule

 os = lazyModule('os')  # import os

 logging = lazyModule('logging')  # import logging
 from gettext import gettext as _

 gtk = lazyModule('gtk')  # import gtk
 dbus = lazyModule('dbus')  # import dbus

 from sugar.activity import activity
 from sugar import env
 from sugar.graphics.toolbutton import ToolButton
 from sugar.graphics.palette import Palette
 import ConfigParser
 import os.path

 vte = lazyModule('vte')  # import vte
 pango = lazyModule('pango')  # import pango

 t1 = time.time()
 logging.debug("terminal.py: imports took %s secs" % (t1 - t0))
 }}}
