The last time was between 3.2 and 3.3. It will be hard to lower the
number of imported modules, given the current semantics (io, importlib,
unicode, site.py, sysconfig...). Python 2's view of the world was much
simpler (naïve?) in comparison.

It would be interesting to know *where* the module import time gets
spent, on a lower level. My gut feeling is that execution of Python
module code is the main contributor.
