[PATCH 0 of 1] CPU chewing patch attempt 3

[Eric Hopper]

This patch should greatly improve the performance when doing a clone of a
large repository.  In testing of a clone over ssh, the ssh process now uses
more CPU time than the Python process and a clone that would've taken many
hours before now takes minutes.
