Gitlab allows incomplete export download

Steps to reproduce

  1. Export a project (Preferably a large one)
  2. Keep refreshing page until the export button appears
  3. Click export button
  4. Note output of top command on Gitlab server, cpu is still pegged at ~99% with gzip command
  5. Note export tarball size
  6. Wait until gzip command is complete in top
  7. Click export button
  8. Note size differential in tarball size

For me, first time was 400MB, second time was ~1.5GB (expected)

What is the current bug behavior?

Export can be downloaded before the archive is complete

What is the expected correct behavior?

Export button does not appear in UI until archive is complete

Relevant logs and/or screenshots

ls -hl
1.5G May 15 21:33  2018-05-15_21-02-086_project_export(1).tar.gz
400M May 15 21:09  2018-05-15_21-02-086_project_export.tar.gz

Note: I'm not sure if the "export is ready" email is sent out before the archive is complete. If so, this bug is even worse.
