If send_pack() always closes fd[1], then I believe "git send-pack
--stateless-rpc --helper-status" would die in print_helper_status(),
called after send_pack(), since fd[1] would be 1, to which
print_helper_status() will try to write. (I don't know what either
--stateless-rpc or --helper-status mean, other than what's obvious
from the code, or if the combination of them makes any sense.)

I don't really have any more time to spend on this issue, so if a more
thorough fix is required, I'm afraid someone else will have to work on
it.
