This problem is really a git bug. For any VCS, I should be able to, in
one terminal, run
while true; do $VCS status; done
and in another terminal, run
$VCS any-damn-operation
and not cause repository corruption or mysterious operation failures.
Maybe it's a good idea for Emacs to work around this particular bug in
git, but there is nothing semantically wrong with what vc-git is doing here.
FWIW, whatever its other faults, hg at least operates correctly here.
