Interesting idea, but YAGNI?

In my work environment (Python 2.7.2, all the heavy lifting done in
C++), startup costs are dominated by dynamic linking of all our C++
libraries and their Boost wrappers:

% time python -c 'import tradelink.snake.v11_2 ; raise SystemExit'

real 0m0.671s
user 0m0.405s
sys 0m0.044s

% time python -c 'raise SystemExit'

real 0m0.022s
user 0m0.011s
sys 0m0.009s
