If I run t5504 under heavy load, it sometimes fails tests 8 and 9, which
make a broken push to the remote. The failure looks like this:
expecting success:
rm -rf dst &&
git init dst &&
(
cd dst &&
git config transfer.fsckobjects true
) &&
test_must_fail git push --porcelain dst master:refs/heads/test >act &&
test_cmp exp act

So it looks like we correctly fail the push, but the expected porcelain
output is missing. I'm _guessing_ what happens is that the local
git-push sees SIGPIPE writing to the remote side, and dies before it
gets a chance to write the message.
I'm not sure if this is something we should be fixing, or if the test is
simply a bit flaky (and we should work around it).
