Hi Stefan,

When you next re-roll the patches for your
'sb/submodule-parallel-fetch' branch, could you please squash
parts of this into the relevant patches. [which would correspond
to commits a93fb7a ("run-command: add an asynchronous parallel
child processor", 22-09-2015) and 58713c8 ("fetch_populated_submodules:
use new parallel job processing", 22-09-2015).]

Thanks!

Also, you might consider renaming some (file local) functions with
really long names, to something a little shorter, like (say):

  handle_submodule_fetch_start_err -> fetch_start_failure
  handle_submodule_fetch_finish -> fetch_finish

(but, as I have said several times, I'm not good at naming things ... ;-)

Also, you could move the definition of get_next_submodule() to be
above/before fetch_populated_submodules() so that you can remove the
forward declaration.

[Note these issues were spotted by sparse and static-check.pl]

HTH

ATB,
Ramsay Jones
