Btw, if you do this, you'll actually see one of the _real_ advantages of pipes. On an SMP system, you'll easily get output like "110%CPU", since now the git-rev-list and the user can run in parallel. Of course, they can do so with temp-files too, but then you have all the "is it a true EOF, or is it just the fact that the writer hasn't written everything yet" problem (and the _normal_ solution for that is to simply not allow any overlapping work).
