For some reason git add . swallowed the whole thing
but git commit did not and I had to split it up. I trimmed the tree a bit
since then by removing c & c++ files ;-)

Ok, that's a bit surprising, since "git commit" actually should do less 
than "git add .", but it's entirely possible that just the status message 
generation ends up doing strange things for a repository with that many 
files in it.

Ahhh. Found it.

It's indeed "git commit" that takes tons of memory, but for all the wrong 
reasons. It does a "git diff-tree" to generate the diffstat, and *that* is 
extremely expensive:

	git-diff-tree --shortstat --summary --root --no-commit-id HEAD --

I suspect we shouldn't bother with the diffstat for the initial commit. 
Just removing "--root" migth be sufficient.
