"git status" is slow. If your changes causes slowdown, it won't likely
stand out while other fast commands may show (read_cache() is used in
nearly all commands). So I tested using the following patch.

The result on linux-2.6 shows about 10-20 us slowdown per each
read_cache() call (30-40 us on webkit, ~50k files) I think your patch
is good enough :-)

That was with -O0 by the way. valgrind/massif shows about 200kb memory
more with your patch on webkit repository (7.497 MB vs 7.285 MB),
using the same test, so memory overhead is ok too.
