Which version of git-svn is this? If it's a public repository I'd like to have a look.

git-svn memory usage should be bounded by:
	max(max(commit-message size),
	    max(number of files changed per revision))

I'm not sure if the size of the files changed per-revision or if the size of the deltas is an issue with git-svn. But if you have a repo with big files and big changes to them, let me know so I can take a look.

Can you also try lowering $inc in git-svn to something lower (perhaps 100)? (my $inc = 1000; in the fetch_lib function) and see if that helps things? Thanks.
