We had been seeing some failures in the git regression testsuite when run on NFS with delegated timestamps enabled. The first patch adds a tracepoint that was helpful for tracking down the problem. The second patch _mostly_ fixes the actual issue. With this, the git regression testsuite is passing a lot more often for me, even when run in the "stress" configuration under kdevops. That said, I'm still seeing an occasional failure that I think may be a problem on the client. I'll send email about that separately.
