I would be _extremely_ cautious to base an argument on one particular setup, using on particular hardware with one particular OS and one particular repository. When it comes to repositories that are worked on actively, git.git is not actually a representative example, it is way smaller than what users deal with. You might be one of those developers privileged enough to have a fast computer. Trying to extrapolate from such a vantage point does the rest of us Git users a big disservice. At this point, I am gently inclined against the presented approach, in particular given that even context menus reportedly trigger the re-scan (which I suspect might actually be a Linux-only issue, as context menus are top-level windows on X11, at least if I remember correctly, and I also seem to remember that they are dependent windows on Aqua and Win32, just to add yet another argument against overfitting considerations onto a single, specific setup). Ciao, Johannes
