I realize that I failed to tell you that I basically spent 2.5 days worth of worktime to figure this out and come up with three iterations of the patch series (you only saw the latest). I want this patch series in git.git, maybe not in the current form, but in one form or another. I don't want to spend any more minute on trying to figure out the same problem with any other regression test (which might not even be as easily worked around as with a semi-simple --upload-pack option). Thank you for wanting to help. Please accept my apologies for expressing in a poor way that I appreciate your eagerness to provide a patch, but that I think nevertheless that it would be better to work on the GIT_TRACE concurrency problem and its resolution via file locks. It would solve that class of problems, instead of that single regression test being flakey. Sorry, Dscho
