title: can't push huge git commit
body: <p>I have a huge 11Gb repo with Android sources.
  I created repo with "git init", then one single commit with "git commit --all ."
  I can't push it to remote repo, when I issue "<code>git push -u origin --all</code>"
  It's stuck with executing 
  <code>"git pack-objects --all-progress-implied --revs --stdout --thin --delta-base-offset --progress"</code> . Speed of reading data is just about 1Mb/s as iotop says. bitbucket refuses with message "fatal: The remote end hung up unexpectedly" and nothing is yet pushed as git does the job locally.
  How to disable this packing and go further?</p>
