Junio,

This makes things _much_ better, however the final commit in the test script still shows a lot of user time:

## time git init real 0m0.005s user 0m0.001s sys 0m0.004s

## time git add . real 0m3.501s user 0m1.268s sys 0m2.159s

## time git commit -q -m 'buurrrrn' -a real 0m2.299s user 0m1.065s sys 0m1.317s

## time git status real 0m1.107s user 0m0.548s sys 0m0.557s

## time git status real 0m1.122s user 0m0.545s sys 0m0.557s

## time git status real 0m1.142s user 0m0.545s sys 0m0.576s

## time git commit -q -m 'hurry' 50/500 real 0m16.944s user 0m15.466s sys 0m1.133s

Cheers, Sean
