Looking closer, I see that the memory suckers do appear to be git, from
dmesg:

Out of Memory: Kill process 17230 (git-repack) score 97207 and children.
Out of memory: Killed process 17231 (git-rev-list).

Just ends like this:

I wasn't running with a version that did repacks; I just suspended the
cvsimport a couple of times and ran a repack manually.
