Thanks. It does not look like it used a lot of memory (~50MB) (viewed
with ms_print). Git allocates 32 bytes per tree and 48 per commit plus
all tree contents, and all that will stay in memory until the end.

This command on git already gives me ~40MB peak. Are you sure you ran
it on your big repo?

echo|valgrind --tool=massif ./git pack-objects --all --stdout > /dev/null
