I've brought this up before, but I don't recall a resolution to it.

We have an NFS-mounted filesystem, and git pull is choking on it.

% uname -a
Linux uhlr.zopyra.com 2.6.9-42.0.2.ELsmp #1 SMP Wed Aug 23 13:38:27 BST 2006 x86_64 x86_64 x86_64 GNU/Linux

It is a really old kernel... Maybe you could try with some of the
recent ones?

I'll see if we can: the machine in question is a high security one,
and not easy to change.  We haven't seen this sort of problem
elsewhere on our newer systems as far as I know.

I extend the part you quoted. The file is opened here:
...
This is strange. The current git should not produce anything like
this (and does not, here). ...

You are absolutely correct.  My comrade ran this with 1.5.0.1 by
mistake.  He reran the strace with 1.5.3.5, and I have replaced
the tarball on my server:

With this minor correction (!), here is the last part from
the last file (strace.out.26001):

Sorry for the mistake.  I think Linus once commented on an alarm
that he found curious in a previous strace I sent for this some
time ago ...
