If your git-status is crashing, you probably have bigger problems (and need to clean up the original, too). But I think a more compelling case is that there may be an ongoing operation in the original repo (e.g., say you are in the middle of writing a commit message) when we do a blind copy of the filesystem contents. You might racily pick up a lockfile. Should we find and delete all *.lock files in the copied directory? That would get ref locks, etc. Half-formed object files are OK. Technically if you want to get an uncorrupted repository you'd also want to copy refs before objects (in case somebody makes a new object and updates a ref while you're copying). I don't know how careful it's worth being. I don't really _object_ to this patch exactly, but it does seem like it's picking up one random case (that presumably you hit) and ignoring all of the related cases. -Peff
