eliminate/reorganize imports to speed up start time:
0.5b:
$ time bash -c 'for i in `seq 100`; do ~/bin/hg > /dev/null; done'
real 0m7.718s
user 0m6.719s
sys 0m0.794s
new:
$ time bash -c 'for i in `seq 100`; do hg > /dev/null; done'
real 0m2.171s
user 0m1.684s
sys 0m0.444s
just python:
$ time bash -c 'for i in `seq 100`; do python -c pass; done'
real 0m0.988s
user 0m0.771s
sys 0m0.207s
Ignoring the fixed cost of loading the Python interpreter, we're 5.6
times faster. With the Python load time, we're still 3.5 times faster.
