[PATCH 0/3] Large transactions in git

[Stefan Beller <sbeller@google.com>]

On Git Merge Wilhelm Bierbaum from Twitter made clear that we'd have problems
with large transactions in git. As I have been working on that series a few
months ago and it still bugs me, I thought about reviving the series.

However the series got stale a few months ago because we were not sure how
to do it right. The first few patches were deemed uncontroversial though,
which I am resending now. 

The first patch contains tests telling us what needs fixing.
The second patch renames the precondition for other tests, as ULIMIT is
a bit generic. The third patch removes the `lock_fd` field from struct
ref_lock which was duplicate information.

That said, this series is not fixing the actual issue, but I'd guess
having these patches is step forward actually.

Thanks,
Stefan
